Kabul: A police official says a suicide bomber has wounded three civilians in an attack outside a popular park in Afghanistan's capital.

Ali Shah Paktiawal says the bomber was on foot and detonated himself on Tuesday in western Kabul next to the walls of the city's historic Babur Gardens.

Paktiawal says three civilians riding in a minibus have been wounded. He says there were no police, soldiers or foreigners in the area at the time.

A massive suicide bombing outside the Indian Embassy in Kabul this month killed more than 60 people and wounded nearly 150. Nevertheless, Kabul has seen fewer attacks this year compared to 2007.
