Islamabad, Sha'ban 17, 1435, Jun 15, 2014, SPA --Pakistani fighter jets Sunday bombed hideouts of militants for the second time in a week, killing over 50 insurgents in the country's north-western tribal region, officials said. The strikes in North Waziristan area targeted mud-houses used by Islamic Movement of Uzbekistan (IMU), a group whose fighters laid a deadly siege of country's busiest airport on June 8, dpa reported. A military statement said most of the dead were Uzbek nationals, believed to be behind a night-time attack at Karachi airport that killed about 40 people, including 10 attackers. The militants from IMU have been based in Pakistan since they were driven out of Afghanistan by international forces in 2001. "There were confirmed reports of the presence of foreign and local terrorists in these hideouts who were linked in planning of the Karachi airport attack," the military said. --SPA 10:51 LOCAL TIME 07:51 GMT www.spa.gov.sa/w
