A suicide bomber killed six people on Saturday in the Iraqi town of Tuz Khurmatu, the scene of deadly clashes between Kurdish and Shiite forces earlier this month, officials said.
The bomber detonated an explosives-rigged vehicle at a checkpoint in the town, also wounding 16 people, according to Shallal Abdul Baban, the official responsible for the area, and a police colonel.
There was no immediate claim of responsibility for the attack, but suicide bombings are a tactic employed by Sunni extremists in Iraq, including the Islamic State militant group, which overran large areas last year.
