A US-Iran deal aimed at ending the Middle East war will be signed at Switzerland's mountainside Burgenstock resort on Friday, the Swiss foreign ministry said. Tehran and Washington announced Sunday they had agreed a memorandum of understanding aimed at ending the conflict, which broke out on February 28 with US-Israeli strikes on Iran and engulfed the Middle East. "At this stage, the signing is scheduled for Friday, June 19, at Burgenstock," Switzerland's foreign ministry said in a statement.
