New blast heard as Kenyan forces sweep for bombs

A new blast has been heard at a hotel complex in Kenya's capital, 24 hours after several extremists attacked.

Witnesses say security forces are conducting a painstaking sweep for any explosives in the Nairobi complex of half a dozen buildings. Emergency responders near the scene appear unperturbed.

Kenya's president has said "all the terrorists have been eliminated" in the attack that authorities say killed 14 people. Some 700 people were evacuated in the overnight security operation.
