A devastating suicide bombing struck a military convoy in Pakistan’s restive Khyber Pakhtunkhwa province on Saturday, June 28, claiming the lives of at least 13 soldiers, according to Reuters.

Some media outlets, however, have reported the death toll as high as 16.

The attack occurred in the North Waziristan district when a suicide bomber rammed an explosive-laden vehicle into the convoy.

A local government official told AFP that the blast left 29 people injured, including 10 army personnel and 19 civilians. Among the wounded were six children.

While no official claim of responsibility has been universally confirmed, several reports suggest that the Tehrik-e-Taliban Pakistan (TTP), also known as the Pakistani Taliban, has taken responsibility for the attack. The TTP, an umbrella organization of various Islamist militant groups, has long operated along the Afghanistan-Pakistan border and has claimed numerous attacks against Pakistani security forces in the past.

The bombing comes just days after Pakistan was appointed chair of the United Nations Security Council’s 1988 Sanctions Committee, which oversees sanctions on the Afghan Taliban, and vice-chair of the 1373 Counter-Terrorism Committee—positions that have drawn both international scrutiny and domestic attention.

In the aftermath of the attack, the Pakistan Army issued a statement alleging Indian involvement in the bombing. India’s Ministry of External Affairs (MEA) swiftly and firmly denied the accusations.

“We have seen an official statement by the Pakistan Army seeking to blame India for the attack in Waziristan on 28 June. We reject this statement with the contempt it deserves,” the MEA said in an official response.
