Three US soldiers have been killed and another wounded in eastern Afghanistan, the Pentagon said.

An Afghan official said the deaths and injury stem from an attack by an Afghan soldier in Nangarhar province, who also died.

In a statement from Washington, the Pentagon did not provide details about what led to the deaths of the US soldiers.

It said the incident was under investigation.

A local spokesman said that the attack took place in the Achin district.

The Taliban have claimed responsibility for the attack, who said in a statement that a Taliban loyalist had infiltrated the Afghan army "just to attack foreign forces".

In March, an Afghan soldier was killed after he opened fire on foreign forces at a base in Helmand province, wounding three US soldiers.
