LONDON - David Cameron has admitted Britain is "paying a high price" for its involvement in Afghanistan following the death of the 300th British serviceman in the conflict.

The Prime Minister said the death of the Royal Marine should prompt questions about why British troops are still in Afghanistan, and how long they should remain there.

He added that the death was a "moment for the whole country to reflect" on the price being paid by British servicemen and women attempting to make the country safe.

His comments were echoed by Major General Gordon Messenger, senior military spokesman, who said it was "entirely right" that the public should ask why British forces were still involved nine years after entering the conflict.

The remarks followed an announcement by the Ministry of Defence that a serviceman injured in an explosion in the Sangin area of Helmand Province on June 12 had lost his life.
