KABUL: The Afghan border police have claimed that the Paksitani forces captured a border checkpoint in Gustha district of Nangarhar province, Afghan media quoting officials reported on Sunday. An official on condition of anonymity said that an Afghan soldier was killed and two others were wounded during the clashes between Afghan and Pakistani forces. Nangarhar is in the provincial capital of Jalalabad and surrounding districts including fearful tribal elders, Taliban militants, some from the Islamic State IS advocates and a number of Salafi preachers who find themselves under increasing pressure to provide ideological and practical support to IS, which most here know by its Arabic acronym, Daesh. Nangarhar has had its share of insurgency-linked security problems since 2001 but the Taliban has never been particularly strong in this part of eastern Afghanistan.
