Kabul: Bombs killed an American service member and two Afghan road construction workers in separate attacks in southern Afghanistan, officials said on Monday.
The southern half of the country, the Taliban heartland, has seen unrelenting violence as the US military builds up its presence in the area.
Most of the 30,000 additional American troops that President Barack Obama has ordered to Afghanistan will be deployed there.
A vehicle carrying the road crew was hit by a roadside bomb Sunday in the Nawa district in Helmand province, according to the Interior Ministry. It said two workers were killed and two were wounded.
The attack occurred a day after a British correspondent and a US Marine were killed by a roadside bomb in the same area.
Sunday Mirror journalist Rupert Hamer, 39, was the first British journalist killed in the conflict.
Hamer and photographer Philip Coburn, 43, were accompanying a US Marine patrol Saturday when their vehicle was hit by a makeshift bomb near the village of Nawa, the British Defense Ministry said. Coburn was seriously wounded.
Afghan President Hamid Karzai on Monday expressed condolences to the family of the British journalist killed as well as to members of the British media community.
Karzai said he appreciated the "brave journalists" who risk their lives in Helmand.
