Kenyan police have arrested more than 650 people in a crackdown on suspected Islamist insurgents a day after six people were killed in bomb attacks in the capital Nairobi.
"This act of cowardice perpetrated against innocent and peace-loving Kenyans who were going about their normal activities is barbaric," Interior Minister Joseph Ole Lenku said in a statement issued on Tuesday.
"So far 657 suspects have been apprehended," he added.
Kenyan police regularly arrest scores of people after similar attacks in sweeping security operations but release most after questioning.
The three blasts on Monday evening targeted two small restaurants and a local clinic in a particularly densely populated area of Eastleigh, an area often known as Little Mogadishu because of its predominantly Somali population.

No one has claimed responsibility for the blasts but Eastleigh has in recent years been the scene of several explosions usually attributed by the police to Islamist extremists.
The attack comes a week after six people died when assailants burst into a church near the port city of Mombasa and opened fire on worshippers.
