Guardian - "Two British soldiers were killed when a man wearing an Afghan police uniform opened fire on them in Helmand province, southern Afghanistan.
The soldiers, from 1st Battalion The Royal Gurkha Rifles, were shot dead at a checkpoint in Nahr-e Saraj on Tuesday, the Ministry of Defence said. Their families had been informed.
Major Laurence Roche, spokesman for taskforce Helmand, said: "The loss of these soldiers is a huge blow to The Royal Gurkha Rifles and everyone serving in taskforce Helmand. Our thoughts are with their families, friends and fellow Gurkhas at this time."
An investigation has been launched into what appears to have been the latest insider or "green-on-blue" attack on coalition troops by members of Afghan security forces, a trend that Nato's secretary general has admitted is sapping trust and has already forced the US military to limit joint operations with Afghan troops.
The surge in attacks has also led to doubts that Afghan forces will be ready for the planned takeover from international troops in 2014.
The latest attack reportedly happened in or near Gereshk, a town at the heart of Helmand's central district of Nahr-e Saraj, the most violent part of the province.
The killing of the Gurkhas would bring the UK death toll from green-on-blue attacks to 11 so far this year. There was only one such British death last year, three in 2010 and five in 2009. In all, 437 UK services personnel or civilians working for the MoD have now died in Afghanistan since October 2001, 394 of them killed in action or dying of their wounds.
More than 50 international troops have been killed by Afghan soldiers or police in 2012. More than 50 Afghan members of the government's security forces have died also in attacks by their own colleagues."
