The chairman of the Afghan High Peace Council, Burhanuddin Rabbani, has been killed with several others in a bomb attack in Kabul, officials say.

Mr Rabbani was killed at his home by a suicide attacker who officials suspect had concealed a bomb in his turban.

He was meeting members of the Taliban at the time. The council leads Afghan efforts to negotiate with the Taliban.

Mr Rabbani is a former president of Afghanistan and also led the main political opposition in the country.
