As police and paramedics rushed to help hundreds of people shot during a country-music festival in Las Vegas, some concert-goers had to tend to people's wounds as best they could while awaiting aid.

One 911 call released Wednesday is from a woman who calmly tells a dispatcher that she has two people with gunshot wounds, including one who is in "very bad shape."

She says the wounded woman is pale and having difficulty breathing as she bleeds from a gunshot wound above her leg.

She says they've tied a belt for a tourniquet and put gauze on the wound but "she seems to be fading pretty fast."

Authorities say 58 people died and hundreds were injured when Stephen Paddock fired assault-style rifles from a hotel suite into the concert crowd.

Police in Las Vegas have released 911 calls by concert-goers and video footage showing the deadliest mass shooting in modern U.S. history.

Frantic calls from concert-goers tell police that people are being targeted by shots and hiding under the stage at a concert venue near the Mandalay Bay hotel.

Video taken from the roof of the hotel shows people in the venue falling and others trying to help them as people run toward exits.

The material was provided Wednesday under a court order more than eight months after the Oct. 1 shooting that killed 58 people and injured hundreds of others.

It's the fifth batch of records made public without comment by Clark County Sheriff Joe Lombardo or his department. The FBI in Las Vegas also declined to comment.

Lombardo has said investigators don't know a motive for the attack and he doesn't think one will be determined.

He said no link has been found to international terrorism.

Authorities say gunman Stephen Paddock acted alone in shooting from the 32nd floor of the Mandalay Bay hotel into an outdoor concert crowd.

The investigation is continuing.
