A PAKISTANI separatist group claimed responsibility for a late night bombing that targeted a convoy with Chinese nationals outside the country’s largest airport, killing two workers from China and wounding eight people, officials and the insurgent group said today.

The attack by the Baloch Liberation Army (BLA) outside the airport in the southern port city of Karachi was the latest deadly assault on Chinese in the country and came a week before Pakistan is to host a summit of the Shanghai Co-operation Organisation, a grouping founded by China and Russia.

The explosion, which the BLA said was the work of a suicide bomber, also raised questions about the ability of Pakistani forces to secure high-profile events or foreigners in the country.
