At least 17 killed in US tornado storms
A system of powerful storms packing tornadoes moved through the south-eastern US, killing at least 17 people including five at an Alabama high school where students became pinned under debris when a roof collapsed.
Crews dug through piles of rubble beneath portable lights at Enterprise High School well into the night, looking for other victims. In the chaotic hours after the storm, reports of the death toll varied wildly.
