Israeli officials: preparing to attack Iran's energy facilities, waiting for US approval On April 5th, according to Reuters, a senior Israeli defense official stated on Saturday local time that Israel is preparing to launch an attack on Iran's energy facilities, but still needs to wait for permission from the United States. He also stated that such attacks are likely to be carried out within the next week. These comments were made after US President Donald Trump issued a 48 hour ultimatum, which has raised concerns about whether the US will support further military action by Israel against Iran.
