Terrorists from the al-Qaeda-backed Somali group al-Shabab attacked a luxury mall in Nairobi on Saturday. The group laid siege to the building, killing at least 62 people and wounding many more. Heavy gunfire could still be heard outside Nairobi’s Westgate Shopping Mall on Monday afternoon. The shots were heard after the government said it had taken back control of the area.
