Two more British soldiers have been killed by explosions in Afghanistan, taking the number of personnel killed since operations began in 2001 to 201.
One, from the 2nd Battalion the Royal Welsh, died in hospital from wounds.
The second, from 2nd Battalion The Royal Regiment of Fusiliers, died after an explosion on Saturday while on foot patrol in Sangin, Helmand province.
Prime Minister Gordon Brown admitted it had been "a very difficult summer", but said progress was being made.
Paying tribute to those who had been killed, Mr Brown said their efforts were helping to make the world safer and that progress had been made in allowing forthcoming Afghan elections to take place.
"We have created space in which we can have Afghan government, Afghan police and Afghan forces and that will make it very difficult for the Taliban and Al Qaeda to reassert themselves," he said.
"Three quarters of the terrorist plots that hit Britain derive from the mountain areas of Pakistan and Afghanistan," he said.
"And it is to make Britain safe and the rest of the world safe that we must make sure we honour our commitment to maintain and keep a stable Afghanistan."
Mr Brown insisted "every effort" was being made to ensure troops had the best security and equipment.
"We have increased dramatically the resources we are spending in Afghanistan to deal with this new kind of threat which is the roadside bomb, the electronic devices, the guerrilla warfare."
The Royal Welsh soldier had been on vehicle patrol near Musa Qala in Helmand province on Thursday morning when he was hit by the explosion.
