LONDON (AFP) - A British soldier shot in Afghanistan more than three years ago has died from his wounds, the Ministry of Defence (MoD) said Friday.

Michael Campbell's death, nearly nine months after British combat forces ended their 13-year operation against the Taleban, brings the total number of British fatalities in the Afghanistan conflict to 454.

Lance Corporal Campbell, from 3rd Battalion The Royal Welsh infantry, died in the Queen Elizabeth Hospital in Birmingham, central England, on Thursday, the MoD said.

Campbell, 32, was on patrol when his unit came under enemy fire and he was struck by a single gunshot to the stomach, the ministry added.

He was flown to Britain's Camp Bastion base and then to the Queen Elizabeth Hospital, which has a specialist unit treating the war wounded from Afghanistan.

Due to its experience with gunshot wounds, the unit also treated Pakistan's Nobel Prize winner Malala Yousafzai, who was shot by the Taleban for campaigning for girls' education.

The last British troops killed in the Afghanistan operation were five men who died in a helicopter crash in April 2014.

The last soldier who died as a result of enemy action was in December 2013.

Defence Secretary Michael Fallon said Campbell was a "proud and professional soldier" who had completed numerous tours of duty in Afghanistan and Iraq.

"It is particularly tragic that Michael Campbell should die of wounds after such a period of time and I send my deepest condolences to his family and loved ones at this sad time," he added.
