Kenya will "hunt down" those responsible for an attack on a shopping centre in Nairobi, the country's president has vowed.

In a television address, President Uhuru Kenyatta said the country had overcome terrorist attacks in the past and would "defeat them again", calling it "the philosophy of cowards."

A senior figure in the Somali militant group al-Shabab has said it is responsible for the attack at the Westgate centre in which at least 39 people have been killed and 150 injured.
