QUETTA: One security personnel was killed on Friday after more than 70 militants entered into the province of Balochistan from neighboring Afghanistan.

Spokesman Frontier Corps Khan Wasey told Dawn.com that more than seventy terrorists and smugglers intruded into Pakistani territory, specifically Balochistan's Killa Saifullah district.

"The FC quickly retaliated and forced most of the terrorists to flee back into Afghanistan," he said.

The spokesman further said that more paramilitary troops were being sent to the border to control the situation.

“Several terrorists and smugglers were injured during the clash with security forces,” Wasey said.

"They took away their injured into Afghanistan," he said, adding that all terrorists were pushed back by security forces.

Some FC personnel were also injured during the gun-battle that lasted for more than three hours at the porous border.

There was no immediate claim of responsibility for the attack.

The incident has come three months after the Afghan forces killed shepherds near Qamaruddin Karez area of neighboring Zhob district.

The Foreign Office had lodged a protest with Afghan authorities for repeated violations at the border.
