Hajj stampede: Saudi Arabia criticised over deaths

Saudi Arabian authorities have defended themselves against criticism over Thursday's stampede near the holy city of Mecca, in which at least 717 people died.

Iran's Supreme National Security Council has accused the Saudis of "incompetence" and urged them to "take responsibility" for the deaths.

But the Saudi health ministry said pilgrims might have disobeyed official instructions.
