Several NATO occupation troops along with Afghan forces were killed on Monday in latest suspected insider attack on the international forces.

"Two US Forces-Afghanistan service members died in eastern Afghanistan today when an individual wearing an Afghan National Security Forces uniform turned a weapon on US and Afghan forces," the US force in Afghanistan said in a statement.

A spokesman for NATO's International Security Assistance Force (ISAF) told AFP that several Afghan soldiers were also killed.

Afghan officials said the incident took place in Wardak, a flashpoint province for Taliban violence on the doorstep of Kabul, which Afghan President Hamid Karzai last month demanded US Special Forces leave.

Interior ministry spokesman Sediq Sediqqi confirmed the location as Jalrez in Wardak and said a delegation had been sent from Kabul to investigate.

The incident comes after the end of a two-week ultimatum by Karzai to remove a US-operated elite force from the troubled province because the Afghan leader said they were fuelling insecurity and instability there.
