The officials further added that clearance operations are still underway by the joint forces, mainly focusing on clearing the mines planted by the Taliban insurgents.
The report confirmed that a massive truck bomb in the centre of Kabul on May 31, which killed at least 90 people, was the deadliest attack since the USA -led invasion that toppled the Taliban in 2001. "The army is being very careful during operations to prevent civilian deaths", Waziri told The Associated Press.
Afghan security forces have retaken a southern district from the Taliban as part of a drive to weaken the insurgents' hold on Helmand province and push them back from around its capital, Lashkar Gah, officials said on Monday.
Provincial governor's spokesman Omar Zwak confirmed that the Afghan forces seized the control of the key areas of Nawa district on Saturday, including the center of the district where the Taliban insurgents had established important fighting positions.
US and North Atlantic Treaty Organisation troops are in Helmand to assist Afghan security forces when needed.
Elsewhere in Afghanistan, the Taliban snatched three border police officers from their auto in the western Herat province, including a woman, and killed them, said Jelani Farhad, the provincial governor's spokesman.
