Two children were killed and three were injured in a suicide attack in Gwadar district of Pakistan's southwest Balochistan province on Friday, a Pakistani government official said.

On August 20, at the Gwadar East Bay Expressway project in Balochistan, Pakistan, a motorcade carrying Chinese personnel was attacked by a suicide bomber, the Chinese embassy in Pakistan confirmed in a statement.

The embassy strongly condemned the act of terrorism, extended sympathy to the injured of both countries, and expressed condolences to the innocent victims in Pakistan.

The Chinese have demanded that Pakistan properly treat the wounded, conduct a thorough investigation on the attack, and severely punish the perpetrators. 

"At the same time, relevant departments at all levels in Pakistan must take practical and effective measures to accelerate, to implement strengthened whole-process security measures and upgraded security cooperation mechanism to ensure that similar incidents will not happen again," the embassy said. 

Noting the security situation in Pakistan has been severe, the embassy reminded Chinese citizens in Pakistan to be vigilant, strengthen safety precautions, reduce unnecessary outings, and take effective security protections.
