CNN: Two massive explosions in Kyiv.

Iran's Islamic Revolutionary Guard Corps said that "the most intense operation against Israel and the United States is set to begin," while state outlets warned that "revenge is coming."

"They want to talk, and I have agreed to talk, so I will be talking to them," Trump told the Atlantic on March 1. He did not say when the talks would take place, noting that some of the previous negotiation officials had been killed in the recent US-Israel strikes.

"Khamenei, one of the most evil people in History, is dead," Trump wrote on Truth Social on Feb. 28. He also said the bombing of Iran would continue for at least the next week.

Ukraine also targeted a Russian ammunition depot and a troop position in the Russian-occupied part of Donetsk Oblast overnight on March 1.

In the latest episode of Ukraine This Week, the Kyiv Independent’s Anna Belokur examines why U.S.-led peace negotiations have so far failed to end Russia’s war, one year after the now-infamous Oval Office clash between Donald Trump and Volodymyr Zelensky.

Belgium has detained the Ethera oil tanker linked to Russia's "shadow fleet," carrying out the operation jointly with French forces, Belgian Defense Minister Theo Francken said.

President Volodymyr Zelensky said that during the final week of winter, Russia launched over 1,720 attack drones, nearly 1,300 guided aerial bombs, and more than 100 missiles of various types against Ukraine.

U.K. Defense Secretary John Healey said he was confident the missiles did not target British military bases, but added that the strikes highlighted the "indiscriminate" nature of Iran's retaliatory campaign.

"Our objective is to defend the American people by eliminating imminent threats from the Iranian regime," Trump said in a video posted to his Truth Social, confirming U.S. invovlement in the strikes.

Russia launched 123 drones at Ukraine overnight, the Air Force said. Ukrainian air defenses intercepted 110 drones.

The number includes 870 casualties that Russian forces suffered over the past day.

"At past negotiations, the Russian side directly said that they would accept the security guarantees offered to Ukraine by the U.S.," the head of the President's Office, Kyrylo Budanov, said on Feb. 28.
