It resembled explosions in 2012 and 2013 that were blamed on Somali militants.<br/> <br />Officials 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.<br/> <br />Kenya's coast is dependent on tourism and has been plagued by attacks blamed on Islamist militants and their sympathizers.
