Which of the following is TRUE of the people suffering from the accident? [br]

Hopes are fading for five people who are missing after a block of flats collapsed in the western Norwegian coastal town of Alesund. It now seems clear a rockslide hit the back of the building early Wednesday, demolishing its lower floors. Fifteen residents were brought out of the modem six-storey block, with two suffering moderate injuries. Rescue teams and sniffer dogs are at the scene, but their efforts are being hampered by fire. Rescue teams from around the region have been called to the town, 350km northwest of the capital Oslo, but are unable to get into the building at present. "The fire, the risk of explosion from the gas tank, possible rockslides and the risk that the entire building could collapse mean we are not able to enter the building at the moment" said a police official, Magne Tjoennoey. Geologists are at the scene to assess the risk of further rockslides.
