KABUL, Afghanistan — At-least Two American soldiers were shot and killed by a member of the Afghan Army in eastern Afghanistan in Laghman Province on Monday when a dispute broke out during a joint American and Afghan patrol, Afghan officials said.

There were unconfirmed reports that the dispute erupted after the convoy was hit by a roadside bomb. NATO confirmed that At-least two of its soldiers had been killed by a member of the Afghan Army.

Noor Rahman, a Laghman police official, said the shooting happened at about 9 a.m. in the Alingar district. “A verbal argument erupted and fire was exchanged,” he said.
The number of so-called green-on-green, or insider, attacks by Afghan police and military forces on their own troops has risen sharply over the past two years, mirroring a similar increase in attacks by Afghan forces on NATO troops

The majority of attacks on Western forces are motivated by outrage or personal disputes, officials say. But officials blame infiltration by the Taliban for most of the Afghan-on-Afghan attacks.
