At least 17 dead in Florida school shooting

At least 17 people are dead after a 19-year-old man opened fire at a high school campus in Parkland, Florida, police have said.

The suspect has been named as Nikolas Cruz, 19, and is a former student at the school who had been expelled. As the attack unfolded students were forced to hide as police swooped in on the building. It is one of the deadliest school shootings since 26 people were killed at a Connecticut school in 2012.
