Prince Harry "kills innocent Afghans while he is drunk", while foreign forces in Afghanistan have failed, a controversial Mujahideen leader in the country has declared.
In an outspoken interview, former Afghan prime minister Gulbuddin Hekmatyar, founder and leader of the Hizb-i-Islamia Party in Afghanistan, accused Britain of being dragged into the war to please its American allies and said its role in the conflict would have no significance after 2014.
Hekmatyar, who was designated a terrorist by the US State Department in February 2003, told the Daily Telegraph: "Britain dragged herself into this unjustified, useless but cruel conflict to please the White House.
"The British did not gain anything, instead they lost blood and treasure.
"They never had a positive role in Afghan affairs and they will not have any significance after 2014.
"I don't understand how the British public accept their children being sent to certain death in order to please American generals."
Of Prince Harry, who spent Christmas in Afghanistan where he is currently serving as an Apache helicopter co-pilot gunner, he said: "The British prince comes to Afghanistan to kill innocent Afghans while he is drunk.
"He wants to hunt down Mujahideen with his helicopter's rockets, without any shame.
"But he does not understand this simple fact that the hunting of Afghan lions and eagles is not that easy! Jackals cannot hunt lions."
The interview comes just weeks after David Cameron signalled that British troops could be withdrawn from Afghanistan even faster after better-than-expected progress by the country's own security forces.
The Prime Minister has announced that UK numbers would be nearly halved to 5,200 this year as part of the plan to end combat operations in 2014, but during a pre-Christmas visit to troops in Camp Bastion he indicated the process could be speeded up further.
But Hekmatyar said: "The fact is that the government has failed. The authorities have lost their credibility completely. They have fallen victims to severe internal disputes and seem hopeless and worried.

"The foreign forces have failed and the situation is worsening day by day. We might face a dreadful situation after 2014, which no one could have anticipated.
"All Afghan groups should agree on the complete withdrawal of all foreign troops by 2014.
"Then a free and fair election should be held.
"We will accept the government of whichever party is voted by the majority of the Afghan people."
The leader said education was as necessary for girls as for boys, but just that they are not taught together.
He added: "Before the withdrawal of invading forces the Mujahideen would like to witness with their own eyes a scene that will teach the invaders to never think of coming this way again.
"And also the others who have bad intentions and are waiting to invade Afghanistan."
