KIEV, July 4 (Reuters) - At least 13 Ukrainian military personnel were killed in separate incidents on Friday in fighting against pro-Russian rebels in eastern Ukraine, a statement from the headquarters of Ukraine's "anti-terrorist operation" said. Nine others were wounded.
The operation, which joins armed forces from the military and interior ministry, resumed on Tuesday after Ukrainian President Petro Poroshenko decided not to renew a ceasefire after numerous violations by rebels.
