KABUL: Eight Afghan policemen were killed by a colleague who turned his gun on them at a checkpoint in the volatile southern Zabul province, an official said on Thursday. The perpetrator escaped the scene in Qalat, the provincial capital, taking weapons and vehicles, said Ghulam Jalani Farahi, Zabul’s deputy police chief. The incident happened at 3:am on Thursday, he said. A Taliban spokesman, Qari Yousaf, said the insurgent group was behind the attack. He told The Associated Press the shooter “is now with us.” Elsewhere, in the Dihrawud district of Uruzgan province, two policemen were killed by a colleague in an apparent personal dispute, said district police chief Shah Muhammad. Insider attacks are commonplace among Afghanistan’s security forces, often carried out by insurgent infiltrators. Most recently, two members of the international military stationed at Kandahar Airfield were shot dead by Afghan colleagues earlier this month. Both were members of Romania’s special forces. Last September, at least one US serviceman was killed when an Afghan solider opened fire on a group of American troops in the eastern city of Jalalabad.That attack was claimed by the militant Hezb-e-Islami group, which this week finalised a peace agreement with the Kabul government, expected to be signed in coming weeks. The international combat operation in Afghanistan largely ended in 2014, when it segued into training and advisory mission with around 13,000 US and NATO troops in the country. About 3,000 of the Americans are engaged in counter-terrorism operations. The Taliban’s war against the Kabul government is in its fifteenth year.
