NAIROBI, Kenya (AP) — Gunman have attacked an upscale mall in Kenya's capital. The Kenyan Red Cross says at least 22 people were killed.

A witness says that before the attackers opened fire with AK-47s, they told Muslims to stand up and leave because non-Muslims would be targeted. Witnesses says the attackers also threw grenades in the Nairobi mall, which was hosting a children's day event.
