NAIROBI (Reuters) - A large blast was heard in the Kenyan capital Nairobi on Monday evening, a Reuters witness reported. Kenyan media said the blast had been at a bus stop, and that people had been injured.
Earlier on Monday a grenade exploded in a Nairobi bar, wounding 13 people, two days after the U.S. embassy in Kenya warned that an attack was imminent as the east African nation fights Islamist militants in neighboring Somalia.
Kenyan Police Commissioner Mathew Iteere said there was no firm evidence yet to link the bar attack to Somalia's al Qaeda-linked al Shabaab rebels. Senior officials from the group declined to comment.
