The local government in Lashkar Gah said one bomber blew himself up, wounding three people, and that police shot dead the other one in the southern town where a Taliban-led insurgency is at its deadliest.
"A suicide bomber detonated in front of the court building in Lashkar Gah. A second one is lying there, he has been shot by police. He`s dead," Daud Ahmadi, a spokesman for the provincial administration, told AFP.
One policeman and two civilians were "slightly" injured, he added.
Interior ministry spokesman Zemarai Bashary told Tolo News television that the men had also been armed with rifles and intended to attack a government building.
Laskhar Gah is among seven towns and provinces where Afghan forces are due to take over security responsibilities from a US-led NATO force in July.
The transition is part of a process that is scheduled to see Afghan security forces take over from US-led troops by 2014, allowing foreign forces to leave.
There are about 140,000, mostly American, military forces in Afghanistan fighting an increasingly deadly Taliban insurgency that broke out after the 2001 US-led invasion of Afghanistan. (*)
