Forces retake two more west districts

Pushing carts loaded with bags, babies and the elderly, hundreds of people fled Mosul on Saturday after Iraqi forces retook two more districts in the west of the city from Islamic State.

After walking for miles, families were taken by bus from a government checkpoint in the south of the city to camps housing more than 410,000 people displaced since the offensive to retake Mosul began in October.

Iraqi forces have taken much of Mosul from the militants who overran the city in June 2014. The military now controls the eastern districts and are making advances in the west.

Islamic State fighters, holding out in the Old City, are surrounded in the northwest and are using booby traps, sniper and mortar fire to defend themselves.

Hundreds of thousands of civilians are still trapped in western Mosul, where Iraqi forces are making slow progress against IS in what is a labyrinth of narrow streets.

As of April 20, some 503,000 people have been displaced from Mosul, of which 91,000 have returned, a spokeswoman for the U.N. refugee agency UNHCR said, citing government figures.

Mosul, Iraq's second-largest city, is the militants' last urban stronghold in the country.
