ORLANDO -- The Orlando Police Department on Monday released audio from the 911 calls made by Omar Mateen the night he went on a rampage at Pulse nightclub, killing 49 people and injuring more than 50 others. 
 
 Circuit Judge Margaret Schreiber on Monday ordered that calls made by Mateen, who died during the massacre, be made public immediately. 
 
 The city previously released a transcript of the calls. 
 
 In the first call, made at at 2:48 a.m. on June 12, Mateen can be heard calmly pledging allegiance to ISIS. His voice rises in anger when he talks about the bombings in Iraq and Syria. 
 
 Mateen emphatically tells a police negotiator that he needs to tell the U.S. government to stop bombings in Syria and Iraq. 
 
 “Who am I speaking with, please?” the negotiator from the Orlando police asks. 
 
 “You are speaking with the person who pledges allegiance to the Islamic State of (inaudible),” Mateen responds. 
 
 The negotiator then asks Mateen to tell him where he is located. 
 
 “No. Because you have to tell America to stop bombing Syria and Iraq,” Mateen says quickly. “They are killing a lot of innocent people. So what am I to do here? When my people are getting killed over there. You get what I’m saying?” 
 
 “I do. I completely get what you’re saying,” the negotiator answers. “What I am trying to do is prevent anyone else from getting ...” 
 
 “You need to stop the U.S. airstrikes,” Mateen interrupts. “They need to stop the U.S. airstrikes, okay?” 
 
 Later in the call, the dispatcher asks Mateen to tell him what he did. 
 
 “You already know what I did,” Mateen answers. 
 
 The negotiator tells Mateen he is trying to keep him safe, and get this situation resolved peacefully. Mateen responds by saying there are vehicles outside with bombs in them. 
 
 “Your people are going to get it and I’m going to ignite it if they try to do anything stupid,” Mateen says. 
 
 The negotiator asks what vehicle, “Because I don’t want to see anybody get hurt.” 
 
 “No. But I’ll tell you this, they can take out a whole city block almost,” Mateen responds. 
 
 In the call, Mateen also calls the Boston Marathon bomber his “homeboy.” He refers to himself as an Islamic soldier, and a Soldier of the God. 
 
 Mateen also indicates that he is wearing a vest, “It’s what they used in France,” he says. But later, he tells the dispatcher he is not wearing a vest after all. 
 
 The call continues with Mateen ranting about Iraq and Syria, and demanding the bombings stop. At one point, he seems to hang up the call. 
 
 The judge who ordered the release of the tapes said Monday she can’t make a decision on whether 232 other calls can be released until she has heard them. 
 
 
 
 Media groups want the calls released so the public can evaluate the police response to the worst mass shooting in modern U.S. history. 
 
 
 
 The city of Orlando says the calls depict suffering and shouldn’t be made public. 
 
 The calls made by Mateen can be heard below, via CBS affiliate WKMG. 

 The man on the phone said he was the person who had just opened fire June 12 inside Pulse nightclub, but Orlando police could not be sure. 
 
 The caller, later identified as Omar Mateen, repeatedly hung up on the Orlando police negotiator who had to call him back more than a dozen times. 
 
 From about 3:15 a.m. to about 3:20 a.m., officers could be heard in the background trying to pinpoint where Mateen might be. The background noise was "sterile," said one officer, as if he were in an office. Or a bathroom, said another. 
 
 "I'm still not convinced this guy's in there," the negotiator said as Mateen's phone rang. Law enforcement officers were going to Mateen's address in Fort Pierce to check whether he was home, and Orlando police pinged his cellphone to establish his location. 
 
 Despite his misgivings, the negotiator, who identified himself as Andy, treated Mateen seriously when they talked. 
 
 He spoke calmly but with a sense of urgency as he tried to pry information from Mateen: where in the club he was, whether there were injured people with him, whether he had explosives or accomplices, what would get him to surrender.

 The nearly 30 minutes of audio of Omar Mateen's 911 calls were released Monday. The written transcripts of the calls were made public in September. 
 
 The attack on the LGBTQ nightclub left 49 people dead and at least 68 injured. Orlando police and Orange County deputies killed Mateen during a shootout just after 5 a.m. 
 
 Mateen was the one who first made contact with police, calling 911 and pledging his allegiance to the Islamic State. He recited part of a prayer in Arabic before telling the dispatcher in English that he "did the shooting." 
 
 Throughout the calls, Mateen repeatedly said he committed the attack to "stop the U.S. airstrikes" on Iraq and Syria.

 "They're killing a lot of innocent people," Mateen said, sounding nervous. "So what am I to do here, when my people are getting killed over there? You get what I'm saying?" 
 
 The negotiator asked him whether he had done something about that. 
 
 "Yes, I have," Mateen said. 
 
 "Tell me what you did? Please?" the negotiator said. 
 
 "No, you already know what I did," Mateen replied, sounding impatient. 
 
 Mateen spoke with the negotiator for only a few minutes at a time, then hung up. 
 
 About 3:10 a.m. the negotiator began calling Mateen back. On the sixth attempt, he picked up. He was calm but terse, uncooperative and at times condescending, calling the negotiator "homeboy." 
 
 At one point, when the negotiator pressed him for a list of grievances, Mateen said, "No, no, no, no, no, Mr. Hostage Negotiator, no. Don't play no [expletive] games with me." 
 
 When the negotiator tried to get him to say whether he had an accomplice with him in the club, Mateen answered, "It's none of your business." 
 
 That phone call lasted about six minutes, but Mateen went silent a few minutes before it ended. 
 
 Police reached Mateen again just before 3:25 a.m. 
 
 "You're annoying me with these phone calls, and I don't really appreciate it," Mateen said. 
 
 "Well, I understand that, but the fact that you appreciate it or not doesn't matter at this point," the negotiator said. "We need to talk, and we need to stay in open communication." 
 
 Mateen told the negotiator not to "talk to me like that." 
 
 The negotiator said he had been passing along the message about the airstrikes but suggested that Mateen come outside unarmed and tell the police himself. Mateen hung up and did not pick up his phone again. 
 
 Orange Circuit Judge Margaret Schreiber on Monday ordered the city of Orlando to immediately release audio of the calls that Mateen made to 911 and received from police that night. Attorneys for two dozen media companies, including the Orlando Sentinel, have pushed for the release of all 911 calls related to the massacre that night.
– The tone of the worst mass shooter in American history ranges from calm to nervous to irritated in a series of 911 calls released by police Monday. In the calls, Orlando gunman Omar Mateen, who called 911 from inside the Pulse nightclub, can be heard pledging allegiance to ISIS, calling himself an Islamic soldier, and describing the massacre as revenge for American bombing in Iraq and Syria, CBS reports. He hung up on police several times. A negotiator who identifies himself as Andy deals calmly and professionally with Mateen, though during one attempt to call him back, Andy tells fellow officers that he's not convinced the man he's dealing with is really inside the nightclub, the Orlando Sentinel reports. Mateen becomes impatient as the negotiator tries to obtain information, telling him it's "none of his business" whether he has an accomplice. At one point, he claims to have vehicles full of bombs outside the nightclub. "Your people are going to get it and I’m going to ignite it if they try to do anything stupid," says Mateen, who was shot dead by police at the end of an attack that killed 49 people and injured 53 others. The AP reports that audio of the calls was released by order of Circuit Judge Margaret Schreiber, who is still considering whether to release another 232 calls to 911 made during the incident. The city of Orlando's lawyers say they shouldn't be made public because they involve suffering and killing.
