US Defense Secretary Leo n Panetta said insider attacks o n NATO forces i n Afghanista n were a "last gasp" tactic by Taliba n insurgents who had bee n unable to make up lost territory.
His comments came after a weekend i n which six NATO troops were killed i n apparent green-on-blue attacks, and appear to contradict commanders o n the ground, who say most of the assaults are the result of cultural conflicts.
"This is a n approach that the Taliba n is resorting to,similar to the use of IEDs (improvised explosive devices),"Panetta said during a visit to Tokyo.
Britain's defence secretary says security has bee n increased at the mai n British base i n Afghanista n after a major Taliba n raid.
Attackers dressed i n US Army uniforms infiltrated Camp Bastio n o n Friday, killing two US marines and destroying six America n fighter jets.
Hammond said attacks like the killing of two British soldiers by a n Afgha n local police officer o n Saturday would not derail the process of training Afgha n security forces so UK troops ca n leave by 2014.
