NEWTOWN, Conn. - Some audio recordings of 911 calls from the Sandy Hook Elementary School shooting were released to the public Wednesday afternoon.

The calls, made to Newtown police describe the scene inside the school as the gunman, Adam Lanza, ran through the hallways, firing rounds into classrooms.

Seven landline calls were made from inside Sandy Hook Elementary School and showed that some of the employees acted as real-time liaisons for police.

Many families of the victims objected to the release of the audio, saying it was unnecessary and a painful reminder of their losses.

The Associated Press had challenged authorities' refusal to release the 911 tapes.

Last week, Connecticut Superior Court Judge Eliot Prescott upheld the Connecticut Freedom of Information Commission's ruling to release calls related to the December 14, 2012 shooting.

The massacre at Sandy Hook left 26 people dead, including 20 children, making it the second-deadliest shooting in U.S. history.

The gunman, Adam Lanza, shot himself at the end of his 11-minute rampage.

The killings in Newtown, about 60 miles outside New York, happened less than five months after a similar bloodbath at a movie theater in Aurora, Colorado, outside Denver.

Those mass slayings triggered a nationwide debate over gun violence, school safety and mental health, a debate that produced some new restrictions on firearms in several states.

Backlash by gun-rights advocates followed.
