KARACHI, Pakistan, Jumada II 20, 1432, May 23, 2011, SPA - Pakistani commandos cornered a team of Taliban militants in a naval base Monday after the insurgents raided the complex the night before, destroying two U.S.-supplied surveillance aircraft and killing at least 12 security officers, the navy said. Between 10 and 15 insurgents armed with grenades, rockets and automatic weapons stormed Naval Station Mehran late Sunday before splitting into smaller groups, setting off explosions and hiding in the sprawling facility. Some or all of them were still holding out 12 hours later, navy spokesman Irfan ul Haq was quoted as saying by the Associated Press. At least 11 navy personnel and one paramilitary ranger were killed, while 14 security forces were wounded, Haq said, adding it was unclear how many militant casualties there were. --SPA 11:02 LOCAL TIME 08:02 GMT www.spa.gov.sa/895500
