Four missiles were fired from across the Pak-Afghan border into Kurram Agency Sunday morning, according to local political administration.

A spokesperson of the local administration said the attack which left locals panicked did not cause any loss of life. However, one missile struck a shop in the Shingak area, another landed near a mosque, and two others in a graveyard at Kachkina, he said.

The spokesperson claimed the missiles were fired from Afghanistan's Paktia province.

Kurram is one of the most sensitive tribal areas as it borders three Afghan provinces and at one point was one of the key routes for militant movement across the border.

Bilateral relations between Pakistan and Afghanistan have been tense as of late, with officials from both sides trading allegations over terrorism.

Pakistan's border crossings with Afghanistan had been sealed in the aftermath of a suicide bombing at the shrine of Lal Shahbaz Qalandar in Sindh ─ the deadliest in a series of recent attacks in the country.

The military leadership had claimed the attacks were carried out by militants operating from safe havens in Afghanistan.

Though trade between the two countries has resumed at Torkham, the border crossing in Kurram Agency's Kharlachi area has been shut since February 16, 2017.
