Iraqi security forces have launched an operation against Al-Qaeda-linked militants in the city of Ramadi.
Large areas of Ramadi, the provincial capital of the western Anbar Province, fell to militant control in late December.
On January 19, heavy clashes were reported between militants and Iraqi police, which were supported by local tribesmen and SWAT teams.
Police have imposed a curfew throughout the city.
Militants led by the Islamic State of Iraq and Levant (ISIS) continue to control large areas of east and northeast Ramadi.
