Summary At least 7 people were killed in a bomb attack on a bus in the Kenyan capital Nairobi.
Seven people were killed and many more wounded in a bomb attack on a bus in a predominantly Somali area of the Kenyan capital Nairobi on Sunday, police and the Red Cross said.
Nairobi police chief Moses Nyakwama said the blast occurred on a bus in the district of Eastleigh, where mainly Somalis or Kenyans of Somali origin live and which has been the target of other attacks in recent weeks.
A suspect, who had suffered slight injuries, was already in custody, he added.
"The information we have is that there were about 25 people in the bus," he said, but revised his earlier report that a device had been thrown into the vehicle.
"It was assembled and left in the bus before it exploded, it was not thrown into the bus," he said.
Nyakwama said the attack happened in a congested street, "so even people passing by got injured".
The blast ripped open the bus, with the roof and sides torn off. The windows were shattered and some seats at the back of the vehicle ripped out.
The force of the blast also sent metal parts of the bus flying, and some were piercing into nearby vehicles and buildings.
The Kenyan Red Cross said on its Twitter account that the death toll was now seven people and appealed for blood donors to help the wounded.
Kenyatta National Hospital s chief executive Richard Lesiyampe said they were treating more than 30 people.
"Most of them have sustained injuries from burns and others have cuts, most of them require blood because of over bleeding," he said.
"We have 34 people in total who are admitted here, but four of them were brought much later after the skirmishes which broke out ... in Eastleigh," he added.
In the wake of the attack, some Kenyans had attacked Somalis in the district, said Nyakwama. But no one had been seriously hurt and the situation was now under control, he added.
"We have deployed an adequate number of officers to maintain peace and I have personally spoken to people there and told them to avoid attacking any specific group, they should let the police do their work in investigating the incident," he said.
Kenya has suffered a wave of grenade and gun attacks, often blamed on sympathisers of Somalia s Shebab Islamist insurgents, since its army went into Somalia last year to flush out the Shebab.
