Another British soldier has been killed in Afghanistan, taking the number of UK deaths in the country to seven in a week.
The serviceman, from the Light Dragoons, died in an explosion near Gereshk in Helmand Province last night.
He was taking part in Operation Panchai Palang, or Panther's Claw, a major assault against the Taliban in the central Helmand river valley ahead of next month's Afghan presidential election.
The soldier's next of kin have been informed.
Lieutenant Colonel Nick Richardson, spokesman for Task Force Helmand, said: "This soldier gave his life for the security of his own country and the freedom of the Afghan people -there is no greater sacrifice than this.
"Our deepest and heartfelt sympathies go to his family and loved ones."
The death takes the number of British servicemen and women killed in Afghanistan since the start of operations in October 2001 to 176.
It has been a grim week for UK forces in the country, with a series of fatalities including the highest ranking Army officer to die on operations since the Falklands.
