2 U.S. troops killed by uniformed Afghans

Kabul, Mar 11 (EFE).- At least two U.S. servicemembers and three Afghan troops died Monday when eight uniformed Afghan security forces members opened fire on them, Tolo television said.

More than 20 others were wounded during the incident in the central province of Wardak, Tolo said.

The deputy chief of police in Wardak, Abdul Razaq Quarishi, confirmed to Efe that the attack occurred "inside a military base" and resulted in the deaths of at least three members of the Afghan security forces.

"The NATO forces are blocking access to the base where the shootout occurred," he said.

At least 50 NATO soldiers, most of them Americans, died last year in attacks carried out by insurgents who had infiltrated the Afghan security forces.

The increase in these types of attacks forced the U.S. military command to reduce its instruction and training programs for members of the local security forces.

Taliban spokesmen publicly acknowledged that their infiltration of the Afghan army and police is a new strategy.
