A roadside bombing has killed 10 workers and wounded 28 on their way to work in southern Afghanistan, according to a local doctor.
Dr. Qayoum Pakhla, the director of Kandahar Hospital, told The Associated Press news agency that the attack happened on Tuesday morning in Kandahar province.
The workers were labourers riding in a truck on their way to work, which involves clearing streams and rivers in the southern province.
There was no immediate claim of responsibility for the attack.
On Monday, a suicide bomber struck a crowded Afghan bazaar, killing four civilians and wounding another 14 in a remote town in the east of the country.
There were no government offices or military patrols in the area where the incident happened, in the small town of Najeel Khail, in the Alishing district of Laghman province, about 100km east of the capital, Kabul.
The explosives were strapped to the bomber's body, a police spokesman said.
A wave of Taliban suicide bombings has accompanied the militants' announcement of the start of their annual spring offensive late last month.
On Sunday, six members of the Afghan security forces were killed when the Taliban stormed a traffic police office and two suicide bombers detonated their explosives in a nine-hour standoff.
