Iraqi special forces are clearing buildings in neighborhoods they entered in eastern Mosul a day earlier, after pushing out Islamic State militants in their drive to take back the city.

Fighting continued Saturday morning, with both sides firing mortars and automatic weapons on each other's positions, while the Iraqi troops also responded with artillery. Clashes were most intense in the al-Bakr neighborhood. Sniper duels played out from rooftops in the mostly residential areas, where the majority of buildings are two stories high.

The special forces launched a two-pronged assault deeper into Mosul's urban center on Friday, unleashing the most intense street battles against IS militants since the offensive to retake the city began nearly three weeks ago. At least seven special forces troops have been killed in the fighting.
