WATCH: Suicide bomber blows herself up in Karachi, 3 Chinese killed

Islamabad, Apr 26: A total of four people, including three foreign nationals, were killed and several others injure after a bomb blast ripped through a passenger van carrying Chinese nationals in the southern Pakistani port city of Karachi on Tuesday.

Banned terror outfit BLA claims the responsibility, saying that a female suicide bomber exploded herself on a van.

CCTV footage of the attack showed a burqa-clad woman standing outside the entrance of the Confucius Institute. The woman detonated herself just as the van neared the institute's entrance.

The banned Balochistan Liberation Army (BLA) linked Majeed Brigade claimed responsibility for the attack on the teachers that took place near China-built Confucius Institute - a non-profit institute teaching Chinese language to local pupils- in the university.

They were identified as Confucius Institute Director Huang Guiping, Ding Mupeng, Chen Sa and Khalid, the Pakistani driver.

The spokesperson added that two others, including Chinese national Wang Yuqing, and Hamid were injured in the blast.

"Academic activities and public dealings will remain suspended at KU on Wednesday to mourn the loss of the Confucius Institute's faculty members," he said.

Balochistan, bordering Iran and Afghanistan, is home to a long-running violent insurgency. Baloch insurgent groups have previously carried out several attacks targeting the USD 60 billion China-Pakistan Economic Corridor (CPEC) projects.
