FLORID - US police officers are on the scene at Marjory Stoneman Douglas High School in Parkland, Florida after receiving reports of gunfire within the school.
The school is on lock down, the Coral Springs Police Department said on Twitter. Students and teachers have been advised to "remain barricaded inside until police reach you."
Lots of ambulances are present at the high school, and several people have been seen being taken out of the school perimeter on stretchers.
The Broward Sheriff Office said: "Here's what we know so far: deputies are responding to reports of a shooting at Stoneman Douglas High. There are reports of victims."
Over the first 23 days of January there were 11 school shootings, according to the New York Daily News. The tragedies have occurred so frequently that activists say the incidents have numbed Americans to the regularity of gun violence.
