A policeman and a civilian were injured on Thursday night after a grenade was thrown towards a police vehicle ferrying arrested suspects, along Biashara street, opposite Marikiti market in Mombasa, officials said.
The attacker escaped after the incident, but police denied that he may have been attempting to rescue his two colleagues who were in the police truck.
Earlier in the evening, the government’s National Disaster Operations Centre had said the blast was from an improvised explosive device that had wounded three people, but Mombasa County commissioner Nelson Marwa confirmed it was a grenade that injured the two.
“Police had arrested the two after gathering some information about them, and were taking them to the police station when another person threw a grenade at their vehicle from behind and ran away, but it exploded outside,” Marwa told journalists at the scene.
The two victims were rushed to hospital and said to be in stable condition.
Last Friday, twin explosions killed at least 10 people in Gikomba market, though no one immediately claimed responsibility.
The Nairobi blasts came a day after government rebuked Britain, the United States, France and Australia for issuing travel advisories on sections of the country including Mombasa, warning of an imminent threats of terror attacks.
Hundreds of tourists left Mombasa ahead of schedule as a result of the advisories, which brought the ailing tourism industry to a near collapse.
Ealier on Thursday, a senior al Shabaab commander said his group had moved its war to Kenya, threatening to launch attacks by teenage suicide bombers within the country.
