Blast at Pak party office injures 10

A blast at the office of a Pakistani political party injured 10 people in the country's northwestern tribal belt yesterday, as the campaign for nationwide polls on July 25 picks up pace. The explosion occurred at the office of cricketer-turned-politician Imran Khan's Pakistan Tehreek-e-Insaaf (PTI), which is one of the main challengers to the incumbent Pakistan Muslim League-Nawaz (PML-N).
