An apparent bomb blast in a Nairobi street on Monday killed one person, injured dozens and left a severed leg hanging from a shattered window. A senior policeman at the scene said the explosion, which also left a mangled corpse in the street and sent passers-by flying through the air, appeared to be a suicide bombing.
"This sort of attack is very unusual for Nairobi," he said. Witnesses saw a man with a package running down the road moments before the blast at around 8 am (0500 GMT), and said the body they saw after the blast was his.
Kenyan police said in a statement they were "pursuing promising leads," and local media said a taxi driver thought to have ferried the attacker was among more than a dozen witnesses helping officers with their enquiries.
The blast occurred during rush hour near the Ambassadeur hotel and a restaurant in the packed central business district. It shattered shop windows and damaged a nearby bus. Local KTN television, however, said a man carrying a grenade was killed when it exploded as he tried to board a bus going to Nairobi's international airport.
