Nairobi — An explosion in a predominantly Somali neighbourhood of the Kenyan capital Nairobi on Wednesday injured at least one person, police sources said.
"One person was injured when an explosive device went off in a supermarket in Eastleigh area," Nairobi police Chief Moses Nyakwama said.
Police said they suspected the explosion was caused by a grenade, adding that they had arrested the injured man and were holding him for questioning.
"The suspect was arrested when the explosive device went off at the entrance of a supermarket, injuring him. His accomplice fled the scene of the 8pm incident. We are interrogating the suspect to establish his involvement," Nyakwama told press.
The Wednesday blast came barely two weeks after another explosion, from what police said was an improvised explosive device, in the same residential area of Eastleigh injured two people.
The residential area is home to many ethnic Somalis as well as Kenyan Somalis.
Earlier this month, attackers also hurled a grenade into a church in the northeastern town of Garissa, close to the Somali border, killing one policeman and wounding 14 people.
Suspected Kenyan supporters of Somalia's Al-Qaeda-linked Shebab insurgents have carried out a string of attacks in protest at Nairobi's decision to send troops into Somalia last year to fight the extremists.
Kenyan troops, now integrated into an African Union force, seized the Shebab bastion of Kismayo in September, a key southern Somali port, and prompting warnings of retaliation from both the insurgents and their Kenyan supporters.
There were no reports of any other injuries from the Wednesday explosion.
