The assault occurred while Chinese engineers were en route from Islamabad to their camp in Dasu, situated in the Upper Kohistan district, when a suicide bomber targeted their vehicle in the Bisham area of the Shangla district.

The Prime Minister of Pakistan, Shehbaz Sharif, has directed a comprehensive joint investigation into the recent terrorist attack on Chinese nationals, following Beijing's call for swift action to ensure the safety of Chinese personnel working in the country.
