In a rare interview with the Iranian government from inside Tehran, Deputy Foreign Minister Saeed Khatibzadeh tells the BBC's Lyse Doucet it would be "a big mistake" for President Trump to join Israel's bombing campaign.

Iran's supreme leader, Ali Khamenei, has warned that any US military intervention in his country will "cause irreparable damage for them". Speaking on state television, the Ayatollah decried what he called "threatening and ridiculous" comments from President Trump, who on Tuesday said Iran should surrender. As Israel's air bombardment of Iran continues for a sixth day, we ask an Israeli minister and a defence official from Mr Trump's first administration whether Israel can achieve its war aims without America's help.

Mr Trump has returned early from the G7 summit in Canada because of the Middle East crisis. Meanwhile, Israel says it has killed Iran’s military chief of staff, Ali Shadmani, in a strike on central Tehran.
