Kabul - At least eight Afghan security forces were killed in a Taliban attack in northern Afghanistan, an official said Wednesday.
The fighters attacked the security checkpoint in Dasht-e-Archi district of Kunduz province early Wednesday, a spokesman for the provincial police, Inamuddin Rahmani, told dpa.
The victims were local police forces, Rahmani said, adding that "five army soldiers were injured as well."
In the hour-long gun battle 15 insurgents were also killed, Rahmani said, adding that the the situation in the area was now under control.
Claiming responsibility for the attack, Taliban spokesman Zabihullah Mujahid said the group killed 11 and injured six local police.
North-eastern Kunduz province is one of the most fiercely contested provinces in Afghanistan.
However, attacks on security posts and bases are increasing across the country and have become a weekly, if not daily, occurrence in recent months.
As the war intensifies, Afghan security forces are overwhelmed and demoralized, contributing to NATO's decision to increase the number of international troops in Afghanistan this year.
Many of the additional soldiers are supposed to help train the Afghan army and police.
