Afghan officials say a suicide bomber blew himself up near a U.S.-led coalition convoy in eastern Afghanistan, killing himself and a child.
At least five other people were wounded in Wednesday's attack in Khost province. A convoy vehicle was damaged, but it is not clear if the wounded include any soldiers.
In a separate incident, in the Kandahar provincial town of Spin Boldak near Pakistan, a bomb explosion killed two people and wounded at least eight others.
Suicide attacks have become frequent in Afghanistan. Most are blamed on insurgents from the former Taleban regime which was forced from power in late 2001.
The U.S.-led coalition has launched a major offensive against Taleban insurgents in eastern and southern Afghanistan. More than 10,000 coalition and Afghan troops are taking part in the operation that began in May. Some information for this report was provided by AFP, AP .
