Two people have been killed and eight others injured in an explosion in central Nairobi, the Kenyan Red Cross has said.
This evening's blast was the second in the capital in three days. A blast near a military base on Wednesday wounded eight people.
Both explosions went off in a Somali neighbourhood of Nairobi known as Little Mogadishu. Kenya has seen a series of small-scale explosions over the last year, many from grenades.
Kenyan media reported that a member of parliament was wounded in the most recent attack.
Al-Shabab sympathisers are suspected in many of the blast attacks, though authorities have not clearly linked all the attacks to al-Shabab or its sympathisers.
