Fierce border clashes erupt between Pakistan and Afghanistan

Border security forces of Pakistan and Afghanistan were engaged in intense clashes Saturday, reportedly resulting in several casualties on both sides.

The war zone is located between the southeastern Afghan border province of Khost and the adjoining Pakistani district of Kurram, as reported by security officials and residents on both sides.

The conflict reportedly broke out when Taliban forces attempted to construct a security outpost on the Afghan side, prompting Pakistani troops to open fire to force the other side to stop the activity.

Pakistani officials maintain neither side can construct new posts unilaterally under mutual agreements regarding the nearly 2,600-kilometer border between the two countries.

Multiple sources reported that ongoing heavy clashes had injured at least five Pakistani soldiers, including an officer, and more than four Afghan border guards.

Pakistan and Afghanistan authorities have not commented immediately on the fighting. This is the second time in as many days that the two countries have clashed over the construction of the disputed Afghan border outpost.

The military tensions come amid Pakistan's persistent allegations that militants linked to the outlawed Tehrik-e-Taliban Pakistan, or TTP, have taken shelter on Afghan soil and are being facilitated by the country's Taliban leaders in orchestrating cross-border terrorist attacks.

"We have, on numerous occasions, presented evidence of the activities of these terror groups, which have hideouts and sanctuaries inside Afghanistan," Mumtaz Baloch, the Pakistani foreign ministry spokesperson, reiterated Thursday.

"We urge the government of Afghanistan to take action against these terror groups and to ensure that these terror groups do not stage terror attacks against Pakistan," she told a weekly news conference in Islamabad.

Taliban authorities deny foreign militant groups, including TTP, are present in Afghanistan, saying no one is being allowed to threaten neighboring countries from their territory.

However, recent United Nations assessments disputed the Taliban claims and backed Pakistan's concerns that TTP operatives had intensified cross-border violence with the help of the de facto Afghan government in Kabul, which no country has officially recognized.

Since the Taliban regained power three years ago, bilateral ties have been strained due to increasing TTP attacks inside Pakistan and occasional border skirmishes, significantly undermining trade and transit ties between Pakistan and landlocked Afghanistan.
