U.S. strike destroys bridge, restricts Islamic State in Mosul - official

BAGHDAD/GENEVA (Reuters) - U.S. forces backing Iraqi troops retaking Mosul from Islamic State carried out an air strike on a bridge spanning the Tigris river, restricting militant movements between western and eastern parts of the city, a U.S. official said on Tuesday.

U.S.-trained Iraqi Counter-Terrorism Service forces are pushing deeper into east of Mosul, the last major city under control of the Sunni hard-line group in Iraq, while army and police units, ShiIite militias and Kurdish fighters surround it to the west, south and north.
