Attacks in Mombasa followed by twin blasts on buses in Kenyan capital
Deadly explosions in Nairobi came a day after two attacks in the port city of Mombasa and as country prepares to welcome Chinese premier

Powerful explosions ripped through two passenger buses in the Kenyan capital yesterday, a day after twin attacks rocked the port city of Mombasa.

Eliud Lagat, deputy head of the bomb disposal unit, said the blasts were caused by improvised explosive devices
Images shown on Kenyan television showed a red passenger bus with a large hole ripped out of its side, and a green bus with its roof and sided buckled by an explosion.
There was no claim of responsibility for the attack, although Kenyan authorities are engaged in a major security crackdown targeting suspected supporters of neighbouring Somalia's al-Qaeda-linked al-Shabab rebels.
The attacks came as Chinese Premier Li Keqiang prepares to visit the country later this week as part of a four-country tour of Africa.
In Mombasa, at least four people were killed in a grenade blast in one of two explosions along the coast of Kenya on Saturday.
