Policemen search a man for weapons as he walked out of Westgate Shopping Centre in Nairobi September 21, 2013. Militant gunmen stormed the shopping mall in Nairobi on Saturday killing at least 39 people, including children, and sending scores fleeing into shops, a cinema and onto the streets in search of safety. Kenyan security forces were still locked in a standoff on Sunday with the al Qaeda-linked militants, who were holding an unknown number of hostages. Picture taken September 21, 2013.

Kenya shopping mall attack

September 22, 2013

Terrified shoppers huddled in back hallways and prayed they would not be

found by the Islamic extremist gunmen lobbing grenades and firing

assault rifles inside Nairobi's top mall on Saturday Sept. 21, 2013.

When

the coast was thought to be clear, crying mothers clutching small

children and blood-splattered men sprinted out of the four-story mall.
