Kenya's Nairobi hit by twin blasts in Gikomba market

Two explosions have struck the Gikomba market area of the Kenyan capital Nairobi, killing at least 10 people and injuring scores, officials say.

It is not clear what caused the blasts but Kenya has been hit by a spate of attacks in recent years.

They have mostly been blamed on the al-Shabab militant Islamist group from neighbouring Somalia.

Hundreds of British tourists have been evacuated from the coastal resort area of Mombasa amid warnings of an attack.

British tour companies have suspended flights to Mombasa, Kenya's second largest city.
