Khalid is a geologist on the expedition. It isn't until they are deep within the caverns and have already been attacked that Khalid explains that he is not the famous geologist Khalid Najmon but is someone that looks a lot like Khalid and was sent with a mission to keep the diamonds and potential of oil from being discovered. Khalid never gives his real name. Khalid has plastic explosives that he has brought on the trip and uses these to try and bring the caverns down and kill everyone inside. Khalid straps a bomb to Jason's waist, although one of the army personnel is able to remove it.
