There have been several instances of attacks around the Strait of Hormuz and Persian Gulf countries in recent weeks. Talks between Iran and the U.S. are at a standstill as the ceasefire threatens to collapse and tip the Middle East back into open warfare, prolonging the worldwide energy crisis sparked by the conflict.

Two people familiar with the situation, including an Israeli military officer, said Israel is coordinating with the U.S. about a possible resumption of attacks. The people spoke on condition of anonymity because they were discussing confidential military preparations.

Speaking to his Cabinet on Sunday, Prime Minister Benjamin Netanyahu said “our eyes are also open” when it comes to Iran. He said he planned a chat with Trump later in the day to discuss the president’s trip to China and “perhaps” other things. “We are prepared for any scenario,” he said.

On Iranian state TV, presenters on at least two channels appeared armed during live programs.

In one program, Hossein Hosseini received basic firearms training from a masked member of the paramilitary Revolutionary Guard. After being shown how to prepare the weapon, Hosseini mimed firing a shot at the flag of the UAE.

On another channel, female presenter Mobina Nasiri said a weapon had been sent to her from a gathering in Tehran’s Vanak Square so she could appear armed on camera. She said: “From this platform, I declare that I am ready to sacrifice my life for this country.”
