Florida student keeps world updated via social media as he dodges bullets during school shooting

A student at Marjory Stoneman Douglas High School in Parkland, Florida, used his phone to keep the world updated via Twitter as bullets flew at the school where a gunman today killed several people.

As the shooting began, Aidan took to Twitter to communicate with the outside world from the school.

"I am in a school shooting right now..." he tweeted.

Following on that first short tweet, Aidan proceeded to keep the world updated with photos and messages from inside the school, as he hid away to stay alive.

"My school is being shot up and I am locked inside. I'm f*****g scared right now," he added shortly after.

His tweet was accompanied by photos showing his colleagues hiding on the floor behind chairs.

Communication went both ways as people could respond to Aidan's tweets to let him know what information they were getting outside the school.

Aidan, a freshman at the school, told the Miami Herald he was in a classroom, where he said he ran for safety after hearing "three to four pops" during a maths test.

At first he thought it was kids being kids and getting up to something but then the fire alarm went off and the students were all herded to the same side of the classroom so no one could see them from outside the door.

Aidan continued to update everyone on his status, and announced he had been released from school.
