At least six people have been killed in three almost simultaneous explosions in part of the Kenyan capital Nairobi that is popular with Somalis.
There was no immediate claim of responsibility.
But in the past attacks in the neighbourhood of Eastleigh – known as ‘Little Mogadishu’ – have been blamed on Somalia’s al-Shabaab Islamist group.
A small mother-child clinic and two restaurants were targeted at a time when people were heading home for the evening.
Homemade bombs or grenades are thought to have been used.
More than two dozen people were hurt, at least nine of them were critically injured.
On Sunday, a man suspected of assembling a bomb was killed when it went off where he lived in Eastleigh, Kenyan media reported.
The Standard daily newspaper, which cited police and witnesses, had said three men who lived with the victim fled in a car shortly after Sunday’s blast.
Officials also recently discovered a large, undetonated car bomb in the coastal city of Mombasa.
Last September al-Shabaab said it was behind the deadly raid on a shopping mall in Nairobi as punishment for Kenya’s military involvement in Somalia. At least 67 people died.
