Afghan security forces on guard after a Taliban attack on March 13, 2012.
At least three Afghan security forces have been killed by Taliban militants in western Afghanistan’s Herat Province, Press TV reports.
The incident took place late Wednesday, after the militants attacked a security checkpoint in the district of Adraskan.
Also in Herat, security forces detained at least five people suspected of carrying out terrorist acts.
On Tuesday, a bomb explosion in eastern Afghanistan’s Kunar Province claimed the lives of at least five Afghan soldiers.
On Monday, 10 Afghan soldiers were killed in an attack on a military checkpoint in southern Helmand Province.
The United States invaded Afghanistan in 2001 under the pretext of combating terrorism.
The offensive removed the Taliban from power, but years into the invasion, insecurity continues to rise across the country despite the presence of thousands of foreign troops in the war-weary nation.
The US-led war in Afghanistan, which has caused record-high civilian and military casualties, has become the longest military conflict in the American history.
