One British soldier has been killed and two injured in an incident in Basra, the Ministry of Defence has confirmed.
Fusilier Gentle was caught in an explosion
A spokesman said it was believed to have been a roadside home-made bomb attack on a British convoy on Monday morning.
The dead soldier has been named as 19-year-old Fusilier Gordon Gentle.
News of the blast came shortly after the Iraqi foreign minister said the handover of power in Iraq was brought forward from 30 June to Monday.
Fusilier Gentle, from Glasgow, was from the 1st Battalion The Royal Highland Fusiliers.
The wounded soldiers are being treated for non life threatening injuries in hospital.
An MoD spokesman said: "Fusilier Gordon Campbell Gentle was killed in an improvised explosive device attack on British military vehicles in Basra."
He added: "The two injured are receiving medical treatment."
Lieutenant Colonel Paul Cartwright, the battalion's commanding officer, paid tribute to Fusilier Gentle.
Lt Col Cartwright said: "As a new member of the battalion, he settled in with ease, happy in the team environment and always willing to help others.
"His enthusiasm for his job immediately caught the eye of his peers and superiors alike."
The attack brings the number of British troops killed in Iraq since the start of the war to 60.
