Afghan policemen stand guard as two US soldiers (C) arrive at the site of a twin suicide attack in a parking lot holding dozens of trucks supplying the NATO-run Kandahar Air Base on June 6, 2012. A twin suicide bombing attack killed 23 people on June 6 in a car park crammed with vehicles supplying a major NATO base in Afghanistan's southern province of Kandahar, police said. A suicide bomber on a motorcycle struck first and as a crowd gathered to help the victims a second bomber walked into their midst and set off explosives strapped to his body, provincial police chief General Abdul Raziq told AFP.
