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

By Saif Hameed and Stephanie Nebehay BAGHDAD/GENEVA (Reuters) - U.S. forces backing an Iraqi army campaign against Islamic State in Mosul 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 Mosul, the last major city controlled by the Sunni hard-line group in Iraq, while army and police units, Shi'ite militias and Kurdish fighters surround it to the west, south and north. Militants have steadily retreated into Mosul from outlying areas.
