Baghdad, Iraq (CNN) -- A female suicide bomber detonated explosives at a provincial council office in western Iraq on Sunday, killing four people and wounding 23 others, the interior ministry said.
The attack took place in Ramadi in Anbar province, about 100 km (62 miles) west of Baghdad.
Most of the wounded were provincial council guards, the interior ministry said.
On Friday, a major Sunni cleric, Abdul Aleem Al-Sa'di, was assassinated in Ramadi by unknown armed men.
In recent months, Ramadi has seen an uptick in attacks, targeting politicians, government officials and religious figures.
Elsewhere Saturday, a car bomb in Kirkuk targeting the Sunni Endowment -- a government agency which oversees the sect's mosques and other sites -- wounded eight people, including the head of the agency, police said.
