Pakistan shuts key border crossing following deadly shrine attack
A second key Chaman border crossing from Pakistan into Afghanistan has been closed, halting trade supplies to the neighbouring country.
The border closure in Pakistan's south-west Baluchistan province comes after a suicide bombing at a Sufi shrine in southern Pakistan which killed 88 people.
The closure was seen as a tactic to pressure Kabul to act against militants who Pakistan said have sanctuaries in Afghanistan.
Earlier, Pakistan closed a border crossing at Torkham, which connects Pakistan to Afghanistan's Nangarhar province.
Islamic State said it was behind the shrine attack.
Pakistani security forces have launched nationwide operations which they said has left more than 100 terrorists dead.
