Kabul, Dec 18 (IANS): At least three people were killed early Wednesday when Afghan Taliban attacked a US forces' supply base in an eastern province of Afghanistan, sources said.

The attack on the base in eastern province of Nangarhar is the second in two months.

"Militants numbered four or five armed with suicide jackets, rocket propelled grenade (RPG) and heavy weapons raided a coalition base in bordering town of Torkham in border area with Pakistan at early Wednesday morning," a security source told Xinhua on condition of anonymity.

One Afghan policeman and two attackers were killed and three policemen were injured in the attack which took place around 5.30 a.m., media quoted the Torkham police chief as saying.

Security forces have cordoned off the area for precautionary measures.

The base is a complex where foreign forces' vehicles and logistic and supply trucks are stationed.

On Sep 2, more than 40 trucks were destroyed and three militants were killed in a similar attack on the same base, for which Taliban claimed responsibility.
