A roadside bomb has struck a passenger bus outside Afghanistan's southern city of Kandahar, killing at least 30 people, including many women and children.
The bus was travelling through Kandahar province from western Nimroz when it hit the improvised explosive device (IED) on Tuesday.
Another blast on the same road had killed three people a day earlier.
A local Taliban spokesman told Al Jazeera that the group was not responsible for the blast.
"Civilians are not our target," he said.
Bismullah Khan, the police chief in the district of Maiwand, said that some of the 39 injured had been taken to a nearby Nato base for treatment.
Others were taken to the main hospital in Kandahar.
Lal Jan, a survivor, told The Associated Press news agency: "An explosion hit the bus. I don't know what happened. When I came to, I got out of the bus and saw that the bus was totally wrecked."
