Two British soldiers have been killed in a bomb attack near Basra in southern Iraq, the Ministry of Defence has said.
Their patrol was targeted by a roadside bomb and small arms fire near the town of Ad Dayr at about 1300 local time.
Another two soldiers were injured - one seriously - and have been taken to the Shaibah Logistics Base by helicopter for emergency medical treatment.
In a separate incident, military boats at a UK base in Basra were hit by mortar rounds or rockets.
The attack started a fire among boats on a waterway inside the perimeter of the Shatt al-Arab Hotel base but no casualties were reported.
The deaths bring the total number of UK soldiers killed in operations in Iraq since the 2003 conflict to 117.
The last British soldier to be killed in Iraq was Matthew Cornish, 29, of the 1st Battalion The Light Infantry, who died after a mortar attack on a Basra base on 1 August.
There are about 7,200 UK personnel in British-controlled southern Iraq, most in the Basra area.
The military convoy was targeted about nine miles (15km) north of the city.
"It is with great regret that we can confirm that two British soldiers have died as a result of an attack on a British patrol," the Ministry of Defence said in a statement.
"One other British soldier was seriously injured, and a further one suffered minor injuries.
"Both have been evacuated for emergency medical care and taken by helicopter to a British Field Hospital at Shaibah Logistics Base."
