AKIPRESS.COM - Gunmen have killed at least four people in an attack on the Chinese consulate in the Pakistani port city of Karachi, BBC reports.

Gunshots were heard at about 09:30 local time (04:30 GMT) outside the consulate in the upmarket Clifton area. Police shot dead three attackers.

Separatist militants who oppose Chinese investment projects in western Pakistan say they carried out the attack.

In another incident on Friday, at least 20 people were killed in a bomb attack in north-west Pakistan.

The blast occurred in a mostly Shia neighbourhood in Orakzai district. Police say a suicide bomber on a motorbike drove into a crowded marketplace.

Pakistan's Shia minority has often been targeted by Sunni extremists.
