KABUL - suicide bomber on a bicycle detonated explosives in central Kabul Sunday, injuring up to five people, a government spokesman told AFP.

"It was a suicide attacker on a bicycle, he was trying to get to a specific area but because of high security the bomber was forced to detonate on a street where there is little activity," said Zemarai Bashary, spokesman for the interior ministry.

The attack comes just two days before Kabul is due to host a major international conference, set to be attended by up to 40 foreign ministers, including US secretary of state Hillary Clinton.
