NATO says 3 civilian contractors killed by Afghan car bomb; death toll now 12

A suicide car bomber attacked a NATO convoy traveling through a crowded neighbourhood in Afghanistan's capital Saturday, killing at least 10 people, including three civilian contractors, authorities said.

The attack struck near the private Shinozada hospital in the capital's Macrorayan neighborhood, the sound of the powerful blast roaring throughout the capital.

The bombing killed at least nine Afghan civilians and one foreigner and wounded 60, said Wahidullah Mayar, a Health Ministry spokesman. U.S. Col. Brian Tribus, a NATO spokesman, said the three contractors had been killed, without elaborating.

Conflicting information is common after such attacks.

Najib Danish, a deputy Interior Ministry spokesman, said the attack destroyed more than a dozen of civilian vehicles.

No group immediately claimed responsibility for the attack, though the Taliban has stepped up its assaults on Afghan security forces since U.S. and NATO troops ended their combat mission in the country last year. The militants also have launched a series of attacks in Kabul in recent weeks following Afghan authorities announcing the death of Taliban figurehead Mullah Mohammad Omar.
