Eight local security guards were shot and killed following an ambush attack near a main US base in Afghanistan's eastern province of Parwan overnight, a local official said on Tuesday.
The guards were ambushed near Bagram base north of Kabul as they were driving home in convoy late on Monday, said district governor Abdul Shakoor Quddusi.
He said the individuals served as security guards for a foreign company (Red) at Bagram airport. The Taliban have increased their attacks against Afghan security forces, and Islamic State group affiliates have been trying to expand their presence by attacking in different parts of the country.
Washington is soon expected to announce an increase in the U.S. military deployment to bolster Afghan forces, who are struggling to contain the Taliban's nationwide offensive.
In April, 100 soldiers had died in a deadly attack by Taliban in Mazar-e Sharif.
Wahida Shahkar said the guards were attacked on their way to work at Bagram airfield, the main US military base in Afghanistan.
