MOMBASA, Kenya, Jan 2 (Reuters) - A grenade attack on a popular nightclub outside the coastal Kenyan city of Mombasa wounded at least 10 people early on Thursday, police said.
The incident occurred at 3:30 am (0030 GMT) at a nightclub frequented by tourists in Diani some 25 km outside Mombasa, they said. It resembled explosions in 2012 and 2013 that were blamed on Somali militants.
"The club was busy with New Year revellers. Three people appeared from the other side of the road and threw a grenade at the night club which (the grenade) exploded injuring 10 people. The attackers escaped on a motor bike," Jack Ekakuro, Kwale area police chief told journalists at the scene.
"It cannot be anything else but a terrorist attack. A grenade is a not a maize cob that any village boy can handle and throw around at will."
Ekakuro did not say who was behind the attack, but the government has in the past put the blame on Somalia's al Qaeda-linked al Shabaab insurgents, who have demanded the withdrawal of Kenyan troops who have joined African peacekeepers fighting the group in Somalia.
Kenya's coast is dependent on tourism and has been plagued by attacks blamed on Islamist militants and their sympathisers.
In September, al Shabaab gunmen attacked a attacked a Nairobi shopping mall, killing at least 67 civilians in the country's worst incident since the 1998 bombing of the U.S. embassy that killed more than 200 people. (Reporting by Joseph Akwiri; Writing by George Obulutsa; editing by Patrick Graham)
