A mortar attack has struck a busy area in a mainly Shiite town south of Iraq's capital, killing at least 22 people and wounding more than 50, authorities say.
The five mortar rounds slammed into a busy market, a residential building and a parking lot about 7pm on Thursday as people returned home from work and shopped in Musayyib, police and hospital officials said.
Police said it appeared the rounds came from the nearby Sunni-dominated town of Jurf al-Sakr, though it wasn't immediately clear who fired them.
Musayyib, about 60km south of Baghdad, is in an area that holds a volatile mix of Sunnis and Shiites and was a flashpoint for some of the worst sectarian violence in past years.
On Tuesday, a parked car bomb in the town killed five civilians and wounded 13, authorities said.
Nobody immediately claimed responsibility for Thursday's attack, but Sunni insurgents frequently target Shiite areas and security forces.
