The US and Iran traded air attacks on Thursday, and President Donald Trump threatened more strikes if Tehran does not immediately agree to a peace deal.

Iranian sources said talks on a preliminary deal had intensified. The US and Iran were exchanging messages on details of a memorandum, but some issues still had to be discussed in detail, including a mechanism for the release of frozen Iranian funds. The US said its latest attacks hit “military surveillance capabilities, communication systems and air defense sites across Iran”.
