A Pakistani diplomat on Saturday called on the international community to block the flow of modern and sophisticated weapons to militant groups in Afghanistan.

“Terrorist armed groups are in possession of billions worth of illicit arms abandoned in Afghanistan,” Syed Atif Raza, a counsellor at the Pakistan Mission to the UN, told an Arria-Formua meeting of the UN Security Council, convened by Sierra Leone.

“We call upon our international partners to recover the vast stockpile of abandoned weapons, prevent their access to armed terrorist groups and take measures to close this thriving black market of illicit arms,” he said.

Pakistani officials have repeatedly claimed that attacks in the country are planned in Afghanistan and that militants use weapons left behind by foreign forces.

The Islamic Emirate, however, has denied the claim, saying Afghanistan is not responsible for Pakistan’s “security failure”.
