The Durand Line and Afghan Pakistani clashes
Frequent violent clashes between Afghan and Pakistani security forces along their disputed border, the colonial-era Durand Line drawn in 1893, have strained ties between Islamabad and Kabul. Afghanistan does not accept the legitimacy of the Durand Line, claiming it is a violation of its sovereignty, while Pakistan believes it is an accepted international border. These tensions will likely worsen following the pending departure of the Americans from Afghanistan.
