Smoke rises from the Westgate mall in Nairobi on September 23, 2013. Kenyan troops were locked in a fierce firefight with Somali militants inside an upmarket Nairobi shopping mall in a final push to end a siege that has left 43 dead and 200 wounded with an unknown number of hostages still being held. Somalia's Al Qaeda-inspired Shebab rebels said the carnage at the part Israeli-owned complex mall was in retaliation for Kenya's military intervention in Somalia, where African Union troops are battling the Islamists.
