South African charity worker, children killed in Taliban attack in Kabul

The latest Taliban strike in Kabul killed a South African father running an education charity and his two teenage children, a family spokeswoman said, as the city police chief resigned after a spate of attacks.

With the US-led Nato war against the Taliban nearing its end, the insurgents have targeted foreign guest houses, embassy vehicles, US troops and a female member of parliament in recent weeks.

Werner Groenewald, 46, his son Jean-Pierre, 17, and daughter Rode, 15, were killed in Saturday's attack on the compound of Partnership in Academics and Development, a small California-based education group.

Werner's wife Hannelie, a doctor, was working at a hospital when the attack began, said Hannelie's sister Riana du Plessis, who is acting as family spokeswoman.

Explosions and gunfire erupted for three hours as Afghan elite commandos battled three militants who were eventually killed.
