At least one woman and a child were killed in a car bomb on Monday night in central Logar province, local officials confirmed on Tuesday.
In addition, three other women were wounded in the explosion.
The incident took place at about 6:30pm local time in Pul-e-Alam, the provincial capital, close to the 4th unit of203 Tandar Military Corps, officials from the corps said.
Officials said that the target was a foreign troops convoy but they did not provide further details about the attack.
In the meantime, Taliban has claimed responsibility for the bombing and claimed that five foreign troops were killed in the explosion.
US forces spokesman Lt. Col. Martin O’Donnell in a statement on Tuesday confirmed that a US mounted patrol in Logar province was attacked by a suicide vehicle-borne improvised explosive device, adding that the attack was ineffective, causing no US casualties and only minor damage to a US vehicle.
"We have also seen, although we cannot confirm, reports from Afghan officials that civilians, including women and a child, were killed and injured in the blast. If true, our thoughts go out to the families of the innocent, who continue to suffer needlessly from the Taliban's violence and their refusal to listen to the call of the Afghan people and take the courageous step towards long-lasting peace," he said in the statement.
