QUETTA: Gunmen on Wednesday killed four paramilitary policemen in an ambush in Pakistan's restive southwestern province of Balochistan, officials said.
The Pakistani Taliban said it carried out the attack, the second time this month it has claimed a deadly assault on security forces.
The Frontier Constabulary officers were attacked while patrolling a railway line in the provincial capital Quetta.
The victims had no chance to retaliate, said Abdul Razzaq Cheema, a senior police official, adding that they recovered 108 Kalashnikov bullet cases from the site.
"We suspect the attackers were at least four people who came on two motorbikes," he said.
A senior official of the paramilitary force confirmed the attack and toll.
On February 3 a suicide bomber killed 11 soldiers in an attack on an army camp in the Swat Valley in the northwest, with the Pakistani Taliban claiming responsibility.
For more than a decade police and troops have been battling Islamist militants and separatist groups in mineral-rich Balochistan, which borders Iran and Afghanistan.
Balochistan is the largest of the country's four provinces but its roughly seven million people have long argued they do not get a fair share of its vast gas and mineral wealth.
