Taliban militants' attack in Kandahar, south of Afghanistan, wounded at least three people on Thursday morning, an eye witness said.
"The attack occurred against a convoy of trucks in 3rd precinct of provincial capital Kandahar city at around 08:30 a.m. local time wounding three drivers," Asmatullah who escaped the attack told Xinhua.
He also said that the attackers were riding motorbikes and made their good escape.
Three trucks were also set on fire by the attackers.
All the trucks were hired and served for NATO-led troops based in Kandahar, Asmatullah further said.
Meantime, police chief of Kandahar province Sardar Mohammad Zazai confirmed the incident and said details would be provided after completion of investigation.
Kandahar, the birthplace of Taliban militants, has been the scene of increasing militancy over the past couple of years.
A joint Afghan and NATO-led forces operation has been going on in parts of Kandahar province since early September.
