An explosion of a heating gas pipe killed at least 11 people and injured 42 others during a wedding ceremony in western Iran, the country's state TV reported on Friday.
The report said five children and five women were among those killed in the explosion, which took place late on Thursday evening in the predominantly Kurdish city of Saqqez, about 450 kilometers (255 miles) west of the capital, Tehran.
Three of the injured were reported to be in serious condition. The TV report said the incident happened following a leak from the pipe feeding the heater inside the wedding hall.
The government announced a one-day public mourning in western Kurdistan province.
Iran occasionally sees such incidents, which are mainly blamed on widespread disregard for safety measures, old and outdated equipment and inadequate emergency services.
In 2005, a fire broke out in a mosque in central Tehran during prayers, killing 59 worshipers and injuring about 250 people.
Climate activist Greta Thunberg arrived in Madrid Friday to join thousands of other young people in a march to demand world leaders take real action against climate change.
The Spanish capital is hosting a two-week, United Nations-sponsored talks aimed at streamlining the rules on global carbon markets and agreeing on how poor countries should be compensated for destruction largely caused by emissions from rich nations.
The talks come as scientific evidence mounts about disasters that could ensue from further global warming, including a study commissioned by 14 seafaring nations due to be published Friday that predicts that unchecked climate change could devastate fishery industries and coral reef tourism.
That could cause hundreds of billions of dollars in losses by 2050, says the report, adding that limiting global warming would lessen the economic impact for coastal countries, but that they also need to adapt to ocean changes.
The presence in Madrid of Thunberg was expected to shift the attention to demands for greater action by non-governmental organizations and a whole new generation of environment-minded activists.
Past appearances by the 16-year-old have won her plaudits from some leaders — and criticism from others who've taken offense at the angry tone of her speeches.
An advocate for carbon-free transportation, Thunberg traveled by train overnight from the Portuguese capital, Lisbon, where she arrived earlier this week after sailing across the Atlantic Ocean from the United States by catamaran.
That became necessary after a sudden change of venue for the COP25 summit following a wave of anti-government protests that hit Chile, the original host.
On arrival, Thunberg was received by a media scrum. Wearing a hoodie and carrying her luggage, the activist and her father Svante quickly walked to a car that drove them out of Madrid's northern station.
A six-story building collapsed in Kenya's capital on Friday, officials said, with people feared to be trapped in the debris.
Associated Press video showed people cheering as one dust-covered person was carried away on a stretcher, one arm outstretched. Shortly afterward the crowd hushed as another person was carried away but covered completely by a blanket.
Nairobi county police chief Philip Ndolo said at least 10 people had been rescued by residents of Tassia estate using their bare hands. Military personnel arrived to assist with the search and rescue operation.
Hundreds of people gathered to watch from nearby buildings as emergency responders prodded at the pancaked structure.
Building collapses are common in Nairobi, where housing is in high demand and unscrupulous developers often bypass regulations.
After eight buildings collapsed and killed 15 people in Kenya in 2015, President Uhuru Kenyatta ordered an audit of all the country's buildings to see if they were up to code. The National Construction Authority found that 58% of buildings in Nairobi were unfit for habitation.
For new Ukrainian President Volodymyr Zelenskiy, a summit meeting with Russia, France and Germany marks a decisive moment in his push to end more than five years of fighting with Moscow-backed separatists in the eastern part of his country. While the Kremlin may share that objective, there are fears in Ukraine that Zelenskiy, a political novice, could give up too much.
Elected in April, the comic actor-turned-politician has said resolving the conflict that has killed more than 14,000 people was his chief priority. Monday's summit in Paris, where he will meet with Russian President Vladimir Putin for the first time, has generated hopes for them to reach a lasting cease-fire.
In a recent video that he recorded in a gym, Zelenskiy argued that trying to end the bloodshed without speaking directly to Russia was similar to working out on a treadmill.
"Some say we can do without such dialogue," he said. "But it's like running this treadmill — you are doing something, you are losing calories, but you remain in place."
The summit comes as a crucial test for Zelenskiy, who also has become embroiled in an impeachment inquiry by the U.S. Congress of President Donald Trump.
In a July 25 phone call, Trump pressed the Ukrainian to investigate political rival Joe Biden, while the White House was withholding about $400 million in essential military aid to Kyiv. The suspension fueled fears among Ukrainians that Washington was turning its back on them or forcing them into a weakened position with Russia.
Zelenskiy has been seeking a meeting with leaders of Russia, France and Germany for months. The first such session was held in Normandy, France, in 2014, shortly after Moscow threw its support behind the separatists in the Donbass industrial region in eastern Ukraine. The conflict erupted weeks after Moscow annexed Ukraine's Crimean Peninsula following the ouster of the country's Russia-leaning president earlier that year.
The U.S. and the European Union responded with an array of sanctions against Russia, making the prospect of lifting them contingent on a peace deal that was brokered by France and Germany. The 2015 agreement, which was signed in the Belarusian capital of Minsk after a series of battlefield defeats suffered by Ukrainian troops, envisaged a wide autonomy for the separatist regions in a diplomatic coup for Russia.
The Minsk accord met the Kremlin's goal of securing self-rule for the rebel regions that would allow Moscow to control its neighbor and dampen Ukraine's aspirations to join NATO.
"Minsk actually more or less gives Russia what Russia wanted to have," said Dmitri Trenin, director of the Carnegie Moscow Center.
The document, which was negotiated by Zelenskiy's predecessor, Petro Poroshenko, outraged many in Ukraine. Its provisions for autonomy of the rebel-held territory and a sweeping amnesty for the separatists were never implemented. Sporadic fighting has continued in the east despite the peace deal, blocking attempts at a political settlement.
Now Putin intends to use the Paris summit to raise the pressure on Zelenskiy to fulfill the Minsk deal, counting on support from French President Emmanuel Macron, who has signaled a desire to normalize ties with Russia. If the 2015 agreement is implemented, it could pave way for a relief from the EU sanctions while allowing Moscow to keep leverage over Ukraine.
Putin and his lieutenants have warned that Moscow won't accept any changes in the Minsk document, particularly on the most sensitive issue of border controls. Under the 2015 agreement, Ukraine could only regain control of the frontier with Russia in the rebel-held territories after those regions hold local elections and receive autonomous status. Pro-Moscow sentiment runs high in those areas, especially the provincial capitals of Donetsk and Luhansk.
"Russia wants the Minsk implemented the way it was formulated and with the logic of the border coming last," Trenin said. "Putin isn't going anywhere to lose."
He noted that even though Putin realizes that it's hard for Zelenskiy to implement the Minsk deal for domestic reasons, the Russian leader "wants to show the Europeans his good faith, his commitment to Minsk, his preparedness to walk his part of the way to reach an agreement."
Zelenskiy said the Minsk deal was bad for Ukraine and vowed to try to revise it, saying he will push for quickly regaining control of the border and demanding the withdrawal of Russian soldiers from the rebel-held territories. The Kremlin has denied that any Russian troops are in Ukraine.
Vyacheslav Nikonov, the head of education committee in the lower house of Russian parliament, argued that the Minsk agreement is "the only thing that keeps Donbass inside Ukraine." He warned that if Ukraine rejects the Minsk deal, as some in Kyiv had suggested, "that means Donbass will become free."
"For Zelenskiy, the only chance to achieve some progress is to keep up with the Minsk accords," Nikonov said.
Many in Ukraine fear that Putin, who has been in power for nearly 20 years, could easily outmaneuver the Ukrainian rookie politician.
"Zelenskiy risks being left alone against the three others, with the leaders of France and Germany playing on the Russian side," said Vadim Karasev, head of the Kyiv-based Center for Global Strategies. "The Minsk agreements left Kyiv little choice — to re-integrate Donetsk and Luhansk on Russian conditions and get a 'Trojan horse,' or lose those territories in a frozen conflict."
Karasev noted that Zelenskiy will try to avoid any radical moves, fearing a backlash from Ukrainian right-wingers and radical nationalists who strongly oppose any rapprochement with Russia. He said the Paris talks could yield some incremental results — such a deal to exchange prisoners or troops pulling back from the front line — but no breakthrough.
Volodymyr Fesenko, head of the Penta think-tank, predicted Zelenskiy will come under strong pressure from those who oppose any deal with Russia irrespective of the outcome of the talks.
"Even if Zelenskiy doesn't sign anything, he will face suspicions and accusations," Fesenko said. "And if he reaches agreements on troops' pullback, they will accuse him of capitulation."
The political party of Poroshenko, the former president, and other opposition groups scheduled a rally in Kyiv for Sunday to warn Zelenskiy against making any concessions.
Opinion surveys indicate broad public support for his peace efforts.
A nationwide poll last month showed 75 percent of respondents backing them. The poll of 2,041 people, conducted by the Democratic Initiatives foundation and the Kyiv International Institute of Sociology, had a margin of error of 2.3 percentage points.
The countries of the OPEC oil-producing cartel and ally Russia were attempting Friday to finalize a deal to cut production in an attempt to support the price of fuel and energy around the world.
The group is expected to prolong a cut of 1.2 million barrels per day that they have agreed on for the past three years. They are also discussing an extra cut worth 500,000 barrels a day, Russian Energy Minister Alexander Novak said.
The price of crude has been held down in recent years by a resurgence in supplies from countries outside OPEC, particularly the United States.
The sticking point in the talks appears to be how to share the cuts among the 14 OPEC countries and nations like Russia that have been coordinating their production with the cartel in recent years.
Saudi Arabia has been bearing the burden of the largest share of production cuts recently. But some countries have been producing more than their expected.
Analysts note that if countries are already not complying with the current agreement, voting for more cuts could be pointless.
"The devil will be in the details when it comes to any official announcement later today," said Justin Low, an analyst at brokerage ForexLive.
He says that Iraq, Nigeria and Russia have not been observing their production limits for various reasons, so part of the decision will be how to ensure greater compliance with any agreement.
Brent crude oil hovered near $63 per barrel Thursday. Prices have fluctuated throughout the year, reaching nearly $75 in April after U.S. sanctions on Iran and Venezuela limited world supply, but lingering trade tensions between the U.S. and China dampened economic expectations pushed prices back down.
West Texas Intermediate, the U.S. benchmark crude, was trading above $58.
Russia has indicated it wants its oil production re-calculated to exclude gas condensate, a liquid byproduct of natural gas production. Condensate is counted against production totals for non-OPEC members but not for members.
Even if members of the cartel cut production, there is more oil coming to market from non-OPEC nations, including the U.S., Canada, Brazil, Norway and Guyana. That could make up for any cuts from OPEC and Russia, who will also be wary of not losing global market share by cutting output too much.
