A suicide bomber killed at least four people and wounded nine others just outside a funeral tent in western Iraq, police said Sunday, according to Reuters.
The bomber detonated an explosive vest outside the funeral near Falluja, 50 km (32 miles) west of Baghdad, for a police officer who was killed in another bomb attack.
Just a day earlier, a car bomb outside a political party's offices in Falluja, in the mainly Sunni Muslim Anbar province, killed five people and wounded 21 others.
Anbar, once the heart of a fierce Sunni insurgency, has been relatively quiet since local tribal leaders began cooperating with U.S. and Iraqi forces against al Qaeda in 2006. But violence appears to have picked up in recent weeks.
Tuesday, Iraqi officials declared a rare vehicle ban across Anbar, Iraq's largest province, after two bomb attacks killed three people in the provincial capital Ramadi. A day earlier, an explosion killed two policemen in the city.
