A working group from China on Friday visited Chinese nationals injured in a terrorist attack in northwestern Pakistan at the Combined Military Hospital in Rawalpindi, near the federal capital Islamabad.

The group, led by Wu Wei, deputy director-general of the Department of External Security Affairs of China's Ministry of Foreign Affairs, was set up to assist Pakistan's local officials in investigating the attack that killed nine Chinese nationals in Dasu on Wednesday.

Three Pakistani nationals were also killed and 39 others injured after an explosion on a bus in the Upper Kohistan district of Khyber Pakhtunkhwa Province.

The blast took place on a shuttle vehicle of the Dasu Hydropower Project, which a Chinese company is contracted to build, as it headed to the construction site in Khyber Pakhtunkhwa.

Chinese Ambassador to Pakistan Nong Rong accompanied the team on the visit.

China's Ministry of Public Security has sent criminal investigation technical experts to Pakistan to join the investigation.
