As the world remembers the assassination of John F. Kennedy, many are reviewing his final day and the evidence around his murder.
In one of the recordings released, a distressed caller is heard saying: "I think there’s somebody shooting in here at Sandy Hook School."
"What makes you think that?" she is asked.
"Because somebody's got a gun. I saw a glimpse of somebody, they're running down the hallway," she replies.
"They're still running, they're still shooting."
In an emergency call from Rick Thorne, whose job title at the time was Acting Head Custodian at Sandy Hook, gunshots are heard as he pleads "it's still going on!"
"I keep hearing shooting. I keep hearing popping," he tells the operator.
Thorne also describes how he thinks the gunman entered the building: "The front glass is all shot out. It kept going on," he says.
During the call the operator is heard asking a colleague to alert state police to the "active shooter".
Towards the end of the recording, loud bangs are heard in the background. This has been edited out of the clip above.
A court order has forced the publication of recordings of emergency calls made to police during the Sandy Hook school shootings in Connecticut, USA, last year.
Operators can be heard responding to witnesses including a teacher and a caretaker who report hearing gunshots.
Prosecutors had tried to block the release of the audio files but a legal challenge from the Associated Press news agency ensured the recordings were made public.

The judge cited the city's dismal finances and $18 billion owed to a multitude of creditors in support of the landmark ruling.
A New York commuter train that derailed, killing four people, was travelling nearly three times faster than the speed limit, officials said.
The seven-carriage train had been travelling at 82mph before entering a 30mph speed limit zone on a curved section of the track where it crashed.
The train's brakes were working but they were applied "very late in the game", National Transportation Safety Board member Earl Weener told reporters.
He added that investigators were considering a driver error being the cause of the crash but had not yet ruled out other possibilities.
The four people killed as a train derailed in the Bronx area of New York City have been named, NBC News reports.
Jim Lovell, 58, James Ferrari, 59, Donna Smith, 54, and Ahn Kisook, 35, were killed when seven carriages flipped onto their sides after the train hurtled around a sharp curve.
Passengers were tossed around like rag dolls during the crash, authorities said.
A federal investigator says there is indication of a link between today's New York commuter train derailment and the derailment of a freight train that occurred in the same location in July.
"We will be looking at that, but at this point, we have no indication that it's a factor," National Transportation Safety Board member Earl Weener said.
Mr Weener said investigators would be on the scene of the crash in the New York city borough of the Bronx for seven to 10 days.
The Governor of New York, Andrew Cuomo, has told CNN that the site where the North-West train derailed was "a dangerous area on the track just by design".

The trains are going about 70 miles per hour coming down the straight part of the track. They slow to about 30 miles per hour to make that sharp curve ... where the Hudson River meets the Harlem River and that is a difficult area of the track.
Four people are confirmed dead after a train derailed near a sharp bend in New York this morning.
