Iran plane crash: Ukrainian jet was 'unintentionally' shot down

Iran has admitted "unintentionally" shooting down a Ukrainian passenger jet, killing all 176 people on board.

An investigation found that "missiles fired due to human error", President Hassan Rouhani said. He described the crash as an "unforgivable mistake".

The military said the jet turned towards a sensitive site belonging to Iran's Revolutionary Guards and was then mistaken for a cruise missile.
