Several people are feared dead and up to 50 injured after a “gas mask-wearing” gunman stormed a Florida high school and opened fire.
Local reports suggest the shooter pulled the fire alarm and opened fire on students as they evacuated the building.

“AVOID THE AREA,” the Broward County sheriff’s office said on Twitter, adding that officers were working on a “developing incident regarding a report of active shooter.”
Television images showed students being led out of the school by heavily armed police officers and an armoured vehicle filled with a SWAT team arriving at the scene.
One injured victim was seen being placed into an ambulance on a stretcher.
Police officers in helmets, bulletproof vests and armed with automatic weapons could be seen stationed at several points around the school.
“What happened was that the fire bell rang and we all thought it was a drill because we had already had a fire drill,” an unidentified student told WSVN 7 News.
“We thought it’s another drill so we didn’t take it seriously and then we heard pops from the other side of the school,” the student said.
Police from neighbouring Coral Springs advised teachers and students in the building to “remain barricaded inside until police reach you.”
CBS News cited the sheriff’s office as saying there were multiple people injured.
