it was a kenyan man named abdul haji. e businessman and father of four received a text message from his brother earlier that morning. >> the message was very brief. it just read at waste gate. terrorists. pray for me. abdul bolted to the mall and was stunned by what he saw when he got there. carnage everywhere. he was terrified for his brother who worked for the kenyan service and received death threats from the same terror group that was now attacking the mall. >> at this point in time, the magnitude of the whole situation dawned on me. >> security forces were just arriving and abdul, licensed to carry a gun, decided in an instant to join them. they entered the mall on the top floor. abdul's brother was still in the mall and not far from catherine walton and her girls on the main floor. he was hiding in a bathroom. abdul worked his way down to the main floor and as he did, his brother managed to escape. >> i reached my phone to try and call him and i see this message on my screen saying, i'm out, i'm safe, please come out
