Fear, hunger and destruction in Mosul Old City as IS under pressure

By John Davison

MOSUL, Iraq, March 17 (Reuters) - After five months of intense fighting, Iraqi forces have begun to drive back Islamic State into the dense and narrow-alleyed Old City of Mosul, with the mosque where its leader Abu Bakr al-Baghdadi declared a caliphate in 2014 firmly in sight.

Iraqi leaders say the battle to recapture Mosul is reaching its final stages, trumpeting each gain made against the militants.

But as Islamic State slows Iraqi advances with stiff resistance, residents trapped inside the Old City with the jihadists describe a desperate siege, with widespread hunger, destruction from U.S.-led air strikes, and civilians living in fear of revenge as the ultra-violent group gets cornered.

"If we hadn't got out this morning, they'd have killed us," said Hisham Sobhi, 41, who fled with his family from their home on the southwestern edge of the Old City on Thursday.

"They (Islamic State) leave some areas, some homes, but sometimes come back again. If they find people still living in areas considered liberated by the army, they kill them," he said.

Mosul is many times larger than any other city Islamic State has held in its self-proclaimed Caliphate, and the fight to drive the militants out, which began last October, is Iraq's biggest ground battle since the U.S.-led invasion of 2003.

Iraqi forces backed by U.S. air power secured the eastern half of the city in January and crossed the Tigris River to fight for the Western side in recent weeks, a decisive battle that would crush the fighters' sway over territory in Iraq.

Sobhi, speaking at a camp south of Mosul, said militants had managed to return to attack areas that remained insecure after Iraqi forces advanced. The area around his home is roughly along the current front line, which he said could shift either way.

Ghassan Thanoun, Sobhi's neighbour, said his 8-year-old son had been trapped under rubble in their home, which was severely damaged in an air raid on their block. The boy, who had not been injured, stood silently, traumatised, and looked at the ground.

"We were scared they'd come back - they consider liberated areas infidel, and accuse you of collaborating with the army," the 50-year-old lawyer said of the Islamic State fighters.

"Yesterday night there was a Daesh attack near the railway station. We didn't want to hang around any longer," he said, using an Arabic acronym for Islamic State.

Islamic State has fought fiercely since retreating into the densely-populated Old City.

Counter-attacks under cover of rain have kept the bulk of the forces from Iraq's elite Rapid Response units and its Federal Police at bay for days on end. Those forces are stationed around the Old City limits and have sent raiding parties to advance on landmarks such as the al-Nuri mosque where Islamic State's leader Abu Bakr al-Baghdadi proclaimed his caliphate.
