China has condemned the blast and asked Pakistan to thoroughly investigate the attack, reported Al Jazeera.
Beijing asked Pakistan to protect the safety of Chinese personnel, institutions, and projects, foreign ministry spokesman Zhao Lijian told a regular news briefing on Wednesday.
Ansari told Reuters that the Pakistani police were investigating. “Looks like sabotage,” he said as he departed on a helicopter for the site.
At least 10 people, including at least six Chinese nationals and two Pakistani soldiers, have been killed in a blast targeting a bus in a remote region of northern Pakistan, multiple sources told Reuters news agency, adding that the toll could rise.
It was not immediately clear whether the blast on Wednesday was the result of a roadside device or something planted inside the bus.
Inspector General Moazzam Jah Ansari, the top police official of Khyber-Pakhtunkhwa, the province in which the incident occurred, confirmed the death of six Chinese nationals, two soldiers, and two locals.
