Afghan authorities say a roadside bomb in Afghanistan's southern Kandahar province killed two police officers and wounded three others.
A provincial spokesman said the intelligence chief of the capital city of Kabul was in the convoy, but the bomb missed him because he was in another car.
Separately, coalition and Afghan forces killed more 30 Taleban fighters in the southern Afghan province of Zabul Saturday. No Afghan or coalition troops were hurt in the battle.
In another incident, an Afghan army commander said fighting in Zabul left two Taliban dead and at least two others captured.
The Taleban ruled Afghanistan between 1996 and 2001, when they were toppled in a US-led invasion. They are now waging an insurgency against the government and its allies.
