After the US killed one of Iran’s senior generals in a drone strike some people were worried we were on the brink of World War 3. Iran threatened revenge, and fired on a US air base in Iraq. But in doing so it made a colossal mistake, downing a commercial aircraft and killing the 176 passengers and crew on board.

The BBC’s Middle East correspondent Quentin Sommerville, who has just returned from the Al Asad air base in Iraq, and the BBC Persian Service’s Rana Rahimpour join us to explain how Iran’s strike has had consequences they weren’t expecting.
