Up to 90 Shia pilgrims have been killed and more than 150 wounded in a double suicide bombing in the central Iraqi town of Hilla, police said.

It was the deadliest in a number of attacks against pilgrims heading to the city of Karbala for a religious event.

At least seven pilgrims were killed and 14 injured in car bombings in Baghdad as they set off for Karbala.

At least three pilgrims were killed in two separate shootings in Latifiya, 30km (20 miles) south of Baghdad.

The attack in Hilla happened in the late afternoon when two bombers wearing explosive vests blew themselves up in a crowd of pilgrims.
