Kenya is marking the one year anniversary of the Westgate siege, when gunmen stormed a upscale shopping centre in Nairobi, killing shoppers and battling security forces.

The Islamist Somali group, al-Shabab, claimed the attack that killed 67 people.

One year on, Kenya's security forces have been accused of failing to act on intelligence reports that an attack was imminent.
