Afghan officials say 15 policemen have been killed in western Afghanistan at the end of a day punctuated by multiple fatalities due to Taliban attacks.
A local official in Farah province says the latest Taliban ambush took place late Wednesday along the region's main highway as a convoy of police patrolled the area. The official said an additional 10 police officers were wounded in the attack.
Earlier Wednesday, insurgent attacks across Afghanistan killed at least 18 people, including a U.S. soldier, four police and three civilians who died in an attack on a joint NATO-Afghan military base.
Authorities say at least 10 Polish soldiers were wounded in the attack in the eastern province of Ghazni, when about 10 insurgents tried to storm the base after detonating a car bomb at the gate. Poland's defense ministry later said 10 insurgents were killed in an hours-long firefight that followed.
The Taliban claimed responsibility.
Earlier Wednesday, a suicide car bomber attacked a coalition convoy in Lashkar Gah, the capital of southern Helmand province. The blast killed four civilians and wounded 15 others.
And separately, authorities say six Afghan drivers were killed and 10 others wounded in western Farah province, when rocket fire hit fuel trucks supplying coalition forces. The inferno also destroyed 40 trucks.
The Taliban also claimed responsibility for that attack.
