Police in Kenya say at least three people been killed and 62 others wounded after two buses in the country's capital, Nairobi, were struck by explosive devices. There has been no immediate claim of responsibility. But Kenya has blamed similar attacks on the al Qaeda-linked Somali group al-Shabaab.

This latest attack comes just a day after four people were killed in two blasts in the coastal city of Mombasa.
