How is the Westgate mall attack remembered 10 years on?

In September 2013 members of the Somalia based militant group al-Shabab attacked and took control of the Westgate mall in the Kenyan capital Nairobi. The attack was the start of a four day siege. 67 people were killed and almost 200 people wounded. The majority of those killed or injured were Kenyans but there were several foreign nationals who died in the attack, including Ghanaian poet and diplomat Kofi Awoonor. Africa Daily’s Alan Kasujja speaks to his son, Afetsi Awoonor, who survived with a gunshot wound to his shoulder. And we hear from BBC editor Ruth Nesoba on the challenge of covering a story like Westgate.
