Three suicide bombers attacked the Chinese consulate in Pakistan"s southern city of Karachi early on Friday but were killed before entering the building.

At least two police officers were killed in the attack, which was claimed by the Baloch Liberation Army (BLA), an ethnic insurgent group that said it opposes Chinese exploitation of natural resources in the country"s southwest. It also describes itself as the Balochistan Liberation Army.

All Chinese staff at the consulate are safe.
