In Pakistan, 27 soldiers were killed and 40 others injured as teenage bomber hits Pak army centre in northwest region. A teenage suicide bomber in school uniform penetrated an elite Pakistani army training centre at Mardan today unleashing his lethal payload in midst of a parade. Police said the condition of some of the injured was critical and the toll could go up.The hit on the Punjab Regimental Centre was one of the worst strikes on the Pakistan army deeply involved for last two years in operations in the restive Khyber-Pakhtunkhawa province bordering Afghanistan to flush out Taliban militants.The blast from the explosives apparently carried in a school bag was so devastating that it blew up soldiers taking part in the parade, scattering their limbs, eyewitnesses said.An attack on the same facility in 2006 had killed 35 soldiers. No particular militant group immediately claimed responsibility for the attack so far.
