Four soldiers have been wounded in a mortar attack on a camp near Amara in southern Iraq, the British Army says.
Two British soldiers died on Saturday
They were hurt during shelling at Camp Abu Naji, where the Queen's Royal Hussars battle group is based.
One was taken to the military hospital at Shaibah, where his condition was stable. Three others were treated for minor injuries at the base.
It comes after two UK soldiers died and a third was injured in a roadside bomb attack outside Basra on Saturday night.
Major Sebastian Muntz, in Basra, said: "The injuries are mostly superficial. We don't normally talk about the injuries in detail.
"There's one chap who's had to be flown down here. It's not a serious injury. So it's - whilst it's a significant attack, there's not been many people badly injured.
The attack, in which a number of mortars fell inside the base in the Maysan province, started at around 4.20am local time.
Two soldiers from the 2nd Battalion Royal Anglian Regiment died on Saturday night and a third was injured. They were on routine patrol in an armoured Land Rover just outside Basra when the device exploded.
The MoD said the 2nd Battalion Royal Anglian Regiment has been based at Ternhill, Shropshire, since 2005.
Its recruits came from Leicestershire, Northamptonshire, Lincolnshire and Bedfordshire.
Their deaths brought to 111 the number of British military casualties in Iraq since 2003.
The dead soldiers' next of kin have been informed but their names have not been released.
The bomb exploded as the patrol approached a bridge. A BBC correspondent said it was detonated by a wire, rather than electronically, making it impossible to counter using radio-jamming techniques.
Defence Secretary Des Browne said his "deepest sympathies and thoughts" were with their families and friends.
But he said the attack would not stop progress in helping Iraqis to safely govern their own country without foreign assistance.
"We shall continue to serve the Iraqi people in the way in which we have for as long as they, through their government, want us to be there."
Last weekend five UK military personnel were killed in a helicopter crash in Basra, including the first British servicewoman to die in action.
