Pakistan says gunmen behind killing of 14 based in Iran

Some 20 people wearing uniforms from the paramilitary Frontier Corps stopped buses in Balochistan province, which were travelling along the coast to megacity Karachi, before gunning down the security officials.

Foreign Minister Shah Mehmood Qureshi said Pakistan had evidence the "terrorist outifts" that carried out the attack have "training and logistic camps inside Iranian areas bordering Pakistan".

Those killed included ten serving with the navy, 3 with the air force and one with the coastguard.

"We have shared this actionable evidence with Iran after due authentication and identified location of the camps," Qureshi said.

Pakistan have created a new Frontier Corps to more effectively control its 950-kilometre long border with Iran, he said.

The construction of a fence along its length has begun, he added.

Balochistan, which borders Afghanistan and Iran, is Pakistan's poorest province and the largest by landmass, with Islamist as well as ethnic Baloch separatists active there.
