ISLAMABAD-Pakistani authorities shut down a second key border crossing into Afghanistan, halting trade supplies to the neighboring landlocked country and increasing tensions between the two nations in the wake of a bloody suicide bombing at a beloved shrine in Pakistan, officials said Saturday.
The border closure at Chaman in southwest Baluchistan province came after an attack on a Sufi shrine in southern Pakistan on Thursday left 88 worshippers dead. The move was seen as an effort to pressure Kabul to take action against militants who Pakistan says have sanctuaries in Afghanistan.
Responsibility for the attack at Lal Shahbaz Qalander shrine in Sehwan was claimed by the Islamic State group.
Pakistan security forces have launched nationwide operations that they say have left more than 100 "terrorists" dead.
Pakistan closed the border at Torkham hours after the bombing and the Chaman border was shut late Friday, said a senior army official.
A second official confirmed the details, saying trucks and shipping containers carrying trade supplies were parked miles away from the border crossings. Torkham connects Pakistan to Afghanistan's Nangarhar province and Chaman is located near Spin Boldak in Kandahar.
The Pakistani officials asked to remain anonymous because they are not authorized to brief the media on the record.
The latest developments come amid media reports that Pakistani troops backed by artillery targeted camps belonging to Jamaat-ul-Ahrar, a breakaway faction of the Pakistani Taliban, near the Afghan border, causing an unspecified number of militant casualties.
Jamaat-ul-Ahrar has claimed to have carried out a number of attacks, including the Feb. 13 suicide assault in Lahore that killed seven police officer and six civilians. Pakistan says Jamaat-ul-Ahrar and the main Tehrik-e-Taliban Pakistan militant groups had been operating from Afghan areas near the Pakistani border and that Kabul in the past ignored Islamabad's pleas to take action against them.
