KANDAHAR: Two attacks just hours apart in the southern Afghan province of Helmand killed 16 people and wounded more than 20 others on Wednesday, officials said.

A suicide bomber on a motorcycle killed 10 civilians and two policemen in the first attack, while an intelligence official was among the dead in a second blast caused by a mine and that was claimed by the Taliban.

"At least 12 people were dead and more than 20 others wounded in a suicide attack in Kajake district of Helmand province," said the Afghan force coordination centre's Mohd Ismail Hotak.

An earlier report said seven policemen were killed.

Two hours later, a local intelligence official, two bodyguards and a civilian were killed in a mine explosion, said Daud Ahmadi, a spokesman for the provincial governor.

"The NDS (National Directorate of Security) deputy director of Nad Ali district, his two bodyguards and a civilian were killed today when a remote-controlled mine planted by the enemy exploded in Nad Ali district," he said.

The Taliban claimed responsibility for the second attack.
