A car bomb blew up as its driver tried to ram a US military convoy in Afghanistan today, while in a separate incident, two Canadian soldiers were wounded in a roadside blast.
The attacks came as the commander of US forces in Afghanistan met Afghan and Pakistani commanders for security talks including discussions of how to combat a wave of bombings.
A Jalalabad police spokesman said US troops had shot dead the suicide car-bomber as he tried to ram a convoy and seconds later his explosives detonated.
US military spokeswoman Lieutenant Tamara Lawrence said the driver was killed in a blast as he approached the convoy.
Violence has surged in Afghanistan since the Taliban announced last month they had launched a spring offensive in their campaign to rid the country of foreign forces.
Dozens of people, including many insurgents, have been killed in a wave of suicide and roadside bombs, ambushes and clashes.
A roadside blast hit a Canadian forces vehicle in the southern province of Helmand, wounding two soldiers. One was slightly wounded and the other was under observation for a wound that was not life-threatening, said a Canadian forces spokeswoman.
The blast happened in an area in which a Canadian and an American soldier were killed during a Taliban attack on a base last month.
A rocket landed in central Kabul late on Wednesday near the US embassy and US and other military bases, slightly wounding an Afghan guard at a state television compound, police said.
