A suicide car bomber has killed at least seven people in Afghanistan's Kapisa province, while Afghan leaders have escaped an attack in neighboring Wardak.

In Kapisa, the bomber detonated his explosives Wednesday near government buildings and the provincial governor's office. At least two police officers were among those killed.

The Taliban claimed responsibility for the attack.

Also Wednesday, Afghan officials say the country's vice president and interior minister were unharmed after rockets hit a police training center in Wardak province.

Vice President Karim Khalili and Interior Minister Bismullah Mohammadi were attending a security meeting at the center when the attack took place. No one else was injured.

In southern Afghanistan, Afghan officials say troops killed 14 insurgents in Kandahar province. The governor's office said nine militants were killed after crossing the Pakistani border, while five were killed while trying to plant roadside bombs.

Elsewhere in the south, NATO says a roadside bomb killed one of its service members Wednesday. No other details were given.
