Islamabad, Dec 15 (PTI) Pakistan on Saturday summoned Iran's ambassador Mehdi Honardoost to record protest against a terrorist attack on a paramilitary convoy on the Iranian border in which six soldiers were killed.

On Friday, about 30 terrorists ambushed a convoy of the Frontier Corps along the Pakistan-Iran border when it was patrolling the area.

Six soldiers were killed and 14 others injured in the "cowardly terrorist attack", the FO said, adding, "The Iranian Ambassador to Pakistan was called to the Foreign Office to lodge a strong protest against the ghastly incident."

Claiming that the militants were operating from the Iranian border area, the FO demanded that Iran should carry out an effective operation against the terrorist group responsible for the attack on its side of the border.

"The need for an effective border coordination mechanism to prevent such incidents in future was also underscored," it said.
