Video shows Kenya jihadis casually killing in mall

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.

The man is seen writhing before a third scene captures him lying in his own blood as the gunman returns and fires more shots. It is believed the man died as a result of his injuries.

The footage also shows terrorists calmly chatting on their mobile phones while scouting the mall for new victims. The al-Qaida linked, Somalia-based terror group al-Shabaab insisted it kept in contact with the men throughout the attack.
