Westgate mall attack: Nairobi shopping centre reopens

Nairobi's Westgate shopping mall, where 67 people were killed in a gun attack in September 2013, has reopened.

Armed al-Shabab militants entered the mall and fired on shoppers, leading to a siege lasting four days.

The reopening comes a week before US President Barack Obama visits Nairobi - a sign, the city's governor said, that the capital was safe.

Karen Allen reports from the Westgate mall.
