Iran plane crash: Western powers suggest missile downed jet
Western leaders suggest an Iranian missile brought down a Ukrainian passenger plane that crashed near Tehran, possibly in error.
The leaders of Canada and the UK called for a full and thorough investigation into the crash, which killed all 176 people on board.
Iran has ruled out a missile strike by its air defences.
The crash came just hours after Iran carried out missile strikes on two airbases housing US forces in Iraq.
