Senior police official Muhammad Ali Gandapur said the explosion occurred when the bomber rammed a vehicle into the workers’ convoy as it traveled from the capital to the Dasu dam, the country’s largest hydropower project, in Khyber Pakhtunkhwa province.
The blast is the third atrocity in a week to rock Pakistan, a strategic ally of China and a key link in Chinese leader Xi Jinping’s ambitious Belt and Road infrastructure initiative, underscoring the mounting security challenges for Chinese projects in the country.
