Prince Harry is a 'jackal' intent on killing innocent people while 'drunk' in Afghanistan, one of the country's feared warlords has said.

Gulbuddin Hekmatyar, who is listed as one of the world's most wanted terrorists by the United States, launched the verbal attack as the Royal spent Christmas in the war-torn country.

Hekmatyar, who was once prime minister of Afghanistan, said Harry is being 'hunted' by the Taliban and in one assault on a base was forced to 'find a hole to hide himself'.

The jihadist also promised that until British 'invaders' leave in 2014 they will be attacked and murdered with even greater intensity.
