At least 31 people have been killed in a stampede during commemorations for the Shia holy day of Ashura in the Iraqi city of Karbala, officials say, the BBC reports.
A health ministry spokesman said another 100 people were injured and warned that the death toll could rise.
The stampede reportedly occurred when a pilgrim tripped while hundreds of thousands were performing a ritual.
Ashura commemorates the martyrdom in battle of the Imam Hussein, a grandson of the Prophet Muhammad, in 680AD.
