Islamabad, Shawwal 23, 1435, August 19, 2014, SPA -- Six civilians died in a roadside bomb attack in north-western Pakistan, the army said, as it pursued its campaign of airstrikes against militants in the country's tribal regions, dpa reported. Militants blew up a school minibus with a remote-control bomb in the Salarzai area of Bajaur, one of seven tribal districts in the north-west. "Six civilians, including three lady teachers, two children and one passerby" were killed, a military spokesman said. In Khyber and North Waziristan, two other tribal districts, jets destroyed five militant hideouts, the army said. "Eighteen terrorists were killed," it said. Pakistan in June launched an operation against the Taliban in the North Waziristan tribal region. According to the army, more than 600 rebels have been killed. --SPA 11:51 LOCAL TIME 08:51 GMT www.spa.gov.sa/w
