Islamic State group fighters are losing large numbers of men along with their grip on Mosul, the Iraqi city they once completely controlled.
Iraqi forces forced Islamic State out of the eastern side of the city in January.
Iraqi government forces have taken back most of it in a US -backed offensive launched in October, including the half that lies east of the Tigris River.
