At least four people were killed and more than 20 wounded in two bomb attacks in the Iraqi city of Fallujah on Saturday.
The BBC reports one blast hit the local headquarters of the Islamic Party.
Police said the first blast was a truck bomb and that the second bomb went off in a car parked on a road leading from the party offices to a hospital.
Roads leading into the city were closed after the attack and a vehicle ban was imposed.
On Tuesday, two bomb attacks killed three people in the provincial capital, Ramadi. A day earlier, an explosion killed two policemen in the city.
The Islamic Party is the main political party in parliament representing the formerly-dominant Sunni minority.
