(KABUL, Afghanistan) — Taliban militants are stepping up attacks on coalition and national security forces in Afghanistan in what may be a bold attempt to regain the momentum in the 10-year-long war.
According to NATO, insurgents got close to a base shared by NATO and Afghan troops in Kandahar province Tuesday but were not able to penetrate the security circle.
Coalition officials say no one inside the base was killed or wounded while the militants suffered several casualties.
Enemy fighters were more successful in a later assault on a police checkpoint in Kandahar city, which left three officers dead.
The latest incident came just days after insurgents dressed in Afghan police uniforms attacked NATO soldiers, resulting in one fatality. The assailants managed to escape.
There have been numerous incidents this year of militants disguising themselves as members of the national army. At least 20 U.S. and coalition service members have died in these surprise encounters.
