An Afghan police official says Pakistan has launched a blistering artillery assault on eastern Afghanistan's Nangarhar province, where a self-declared affiliate of the Islamic State group is based.
Gul Agha Roohani, provincial police chief of Nangarhar, says Pakistan fired several artillery rounds early on Friday into the province's Lalpur district, near the Afghan-Pakistan border.
There was no immediate comment from Pakistan, where a suicide bombing on Thursday killed 75 people and wounded scores more at a Sufi shrine in southern Sindh province.
The attack was claimed by the Islamic State group.
Pakistan says Thursday's attack and other recent bombings have been masterminded by militants who hide across the border and use sanctuaries in Afghanistan.
