Saudi Arabia's civil defense directorate says at least 150 people have been killed in a stampede at the annual hajj pilgrimage.

The directorate says at least 400 other pilgrims were injured in Thursday's stampede, which took place in Mina, on the outskirts of the holy city of Mecca.

Some 2 million people are taking part in this year's hajj pilgrimage, which began Tuesday.
