(AFP) -  A suicide bomber rammed his explosives-packed car into a British embassy vehicle in Kabul on Thursday, killing one British citizen and at least five Afghans, Kabul police said in a statement.

"One British national was killed in today's attack," police spokesman Hashmat Stanakzai said in an emailed press statement.

The British embassy made no immediate comment after earlier confirming that a number of embassy staff had been injured.
