ISLAMABAD: As tensions between Islamabad and Kabul spiked after the Chitral cross-border raid by terrorists from Afghanistan, the Afghan chargé d' affaires was summoned to the Foreign Office and told that such attacks would not be tolerated any further.

“The activities of the terrorists are a matter of great concern … They cannot be allowed to continue such blatant attacks from across the border,” the Afghan diplomat was told in a strongly worded protest.

The Chitral attack that left 25 security personnel dead was the latest in a series of attacks launched by terrorists having sanctuaries in Afghanistan's Kunar and Nooristan provinces.

Afghan ambassador Umar Daudzai was earlier handed a demarche after a similar attack in June. But, officials regretted that the Afghan authorities did little to address Pakistan's concerns. This aspect was particularly underscored in the latest protest.—Staff Reporter
