Battle for Mosul: Iraqi Army last battle in ISIS Headquarters
Since launching an offensive on October 17 to oust IS from its last Iraqi stronghold, pro-government forces say they have recaptured almost half of eastern Mosul and are edging towards the Tigris river that divides it.
The elite Counter-Terrorism Service has retaken several eastern neighbourhoods and was fighting on Friday in Al-Noor district, just over three kilometres (two miles) from the river.
Hashed al-Shaabi (Popular Mobilisation) paramilitary forces have been fighting on a western front. On Thursday they were clearing Tal Abtah of bombs and booby traps after a fierce, days-long fight to retake it.
Iraqi forces on the southern front have halted within striking distance of IS-held Mosul airport, while the northern front has frozen in recent days.
