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 (IS) militants.
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.
"We left with no water, food or electricity," said 63-year-old Abu Qahtan, the elder of a group of 41 people from five families. "We left with the clothes on our backs."
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.
IS militants, holding out in the Old City, are surrounded in the northwest and are using booby traps, sniper and mortar fire to defend themselves.
On Saturday, artillery and gun fire could be heard as families arrived from Hay al-Tanak district which they said was still half controlled by the militants.
Troops, backed by helicopters, were moving towards the al-Nuri mosque where, nearly three years ago, IS leader Abu Bakr al-Baghdadi announced his self-declared caliphate spanning parts of Iraq and Syria.
A Reuters reporter, standing within sight of the mosque, saw heavy smoke in that area after an air strike.
The U.S.-trained Counter-Terrorism Service (CTS) has retaken the nearby al-Thaura and al-Saha districts, statements said.
CTS commander Major General Maan Saadi said his troops were linking up with Iraq's Federal Police moving in on the Old City from a different position.
"We are completing the encirclement of the terrorists in the Old City," he told Reuters.
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.
