(Warning Graphic Content) The Independent: Chilling new CCTV footage has emerged of terrorists casually gunning down shoppers during the attack on Kenya’s Westgate shopping centre last month. In a video obtained by CNN, one man can be seen hiding behind a supermarket kiosk as the gunmen storm the mall. As shoppers run for their lives, a terrorist casually approaches the cowering man and fires a bullet into his body from close-range. In the next clip the man is seen writhing in agony, before a third scene captures him lying in a pool of his own blood as the gunman returns and fires more shots at him. It is believed the man died as a result of his injuries. As the mother – who had already been shot in the thigh by a terrorist – leads her children from the store using a shopping trolley to carry one of her injured offspring, she is seen being followed by a terrified, blood-soaked teenage girl, and finally by one of the gunmen. The footage also shows terrorists calmly chatting on their mobile phones while scouting the mall for new victims. The al-Qa’ida linked, Somalia-based terror group al-Shabaab insists it kept in contact with the men throughout the attack. During rare quiet periods during the subsequent four-day siege, the Western-dressed Islamist terrorists are seen taking turns to kneel down and pray as their assault-rifle wielding colleagues stand guard.
