A convoy of buses headed to Mariupol on Thursday in another attempt to evacuate people from the besieged port city, while Russia pressed its attacks in several parts of Ukraine ahead of a planned new round of talks aimed at ending the fighting. After the Russian military agreed to a limited cease-fire in the area, the Red Cross said its teams were traveling to Mariupol with relief and medical supplies and hoped to help pull civilians out of the beleaguered city on Friday. Previous attempts at establishing a similar humanitarian corridor have fallen apart. Russian forces, meanwhile, shelled suburbs of the capital that Ukraine recently retook control of, a regional official said. New attacks in the area where Moscow had promised to de-escalate further undermined hopes of a resolution to end the war on the eve of a new round of talks. A day earlier, Ukrainian officials reported that Russian shelling on the outskirts of Kyiv and around another city where it had vowed to ease up. Russia’s Defense Ministry also reported new strikes on Ukrainian fuel stores late Wednesday, and Ukrainian officials said there were artillery barrages in and around the northeastern city of Kharkiv over the past day. Despite the fighting raging in those areas, the Russian military said it committed to a cease-fire along the route from Mariupol to the Ukraine-held city of Zaporizhzhia from Thursday morning.

Food, water and medical supplies have all run low during a weekslong blockade and bombardment of the city. Civilians who have managed to leave have typically done so using private cars, but the number of drivable vehicles left in the city has also dwindled and fuel stocks are low. The International Committee of the Red Cross, which is helping run the evacuation, said its teams have already left for Mariupol. “It’s desperately important that this operation takes place,” the Red Cross said in a statement. “The lives of tens of thousands of people in Mariupol depend on it.” As the new evacuation attempt was announced, evidence emerged that a Red Cross warehouse in the city had been struck earlier this month amid intense Russian shelling of the area. In satellite pictures from Planet Labs PBC, holes can be seen in the warehouse’s roof, along with a painted red cross on a white background. The aid organization said no staff have been at the site since March 15. Talks between Ukraine and Russia were set to resume Friday by video, according to the head of the Ukrainian delegation, David Arakhamia, six weeks into a bloody war that has seen thousands die and a staggering 4 million Ukrainians flee the country. But there seemed little faith that the two sides would resolve the conflict soon, particularly after the Russian military’s about-face and its most recent attacks. Russia had promised during talks in Istanbul this week that it would de-escalate operations near Kyiv and Chernihiv to “increase mutual trust and create conditions for further negotiations.” Ukrainian President Volodymyr Zelenskyy and the West were skeptical. Soon after, Ukrainian officials reported that Russian shelling was hitting homes, stores, libraries and other civilian sites in or near those areas. Britain’s Defense Ministry also confirmed “significant Russian shelling and missile strikes” around Chernihiv.
