A suicide bomber in Iraq has killed at least 27 people in an attack on a bus carrying Shia pilgrims, police say.
The explosion took place just outside the Sunni-majority city of Samarra, north of Baghdad.
A police source at a hospital in Samarra told Reuters news agency that a number of women and children were among the injured.
Violence in Iraq has dropped sharply since the height of the conflict in 2006-07, but bombings are still common.
Samarra houses an important mosque and shrine to the 9th Century imam Hassan al-Askari.
On Thursday, at least eight people were killed in a car bomb attack in the town of Dujail on pilgrims heading to Samarra to celebrate Saturday’s annual commemoration of the imam’s death.
