Israel struck Evin prison in northern Tehran on Monday, a potent symbol of Iran's governing system, in what Israel called its most intense bombing yet of the Iranian capital a day after the United States joined the war.

Iranian Foreign Minister Abbas Araghchi warned that any military action by the U.S. in the escalating war with Israel would be "very, very dangerous for everybody."
