At least 15 people have been killed in a suicide bomb attack on a wedding, an Iraqi security official has said.
Five suicide bombers took part in the attack in the village of Ein Tamer, south of the capital, Baghdad, on Monday, but the other four were killed by security forces, said Lieutenant General Qais al-Mohammedawi.
He said the attackers were members of the Islamic State group, which has stepped up attacks on security forces and the country's Shiite majority in recent months as it has suffered a string of battlefield setbacks.
Ein Tamer is about 25 miles (40km) west of the Shiite holy city of Karbala.
