text:  We didn't immediately realise what was going on because we couldn't look outside. It was a windowless room. Then there was another explosion and the walls started shaking and the equipment on the walls started shaking as well. The fire alarm went off and the lights on the equipment started flashing. A nurse rushed in. She began to disconnect my son from the drips and said we needed to leave the room immediately and go out, at least into the corridor, where we would be safer.
