 Nurse Jacintha Saldanha was found dead after taking the prank call on Catherine 
 
 An Australian radio network at the heart of a hoax targeting Prince William's pregnant wife canceled the show responsible for the prank on Monday, expressing deep regret for the death of a nurse who took a call from the DJs involved. In a statement to the stock exchange, Southern Cross, which has media interests throughout Australia, said that it had decided to halt all prank calls by its broadcasters. In a statement, the radio station's owner, Southern Cross Austero Media, said it had suspended advertising on 2Day FM until further notice, ended Greig and Christian's Hot 30 show and suspended prank calls across the company. The DJs, Mel Greig and Michael Christian, who were impersonating Queen Elizabeth and Prince Charles, called the hospital Tuesday and gained some information about the condition of Catherine, Duchess of Cambridge -- which they subsequently played on air. On Friday, the nurse who transferred the call through to the ward, Jacintha Saldanha, was found dead after apparently committing suicide. Rhys Holleran, chief executive of Southern Cross Austereo, which owns 2Day FM, said the station called the hospital five times to discuss what it had recorded before going to air. Greig and Christian also apologized in interviews with the Australian TV shows "A Current Affair" and "Today Tonight" on Monday. "There is nothing that can make me feel worse than what I feel right now," Greig said on "Today Tonight." Christian told "A Current Affair" the prank had become "a tragic turn of events that I don't think anyone could have predicted or expected." "Shattered, gutted, heartbroken and obviously you know... our deepest sympathies are with the family and the friends," he told Nine. The mother volunteered to quiz her daughter despite apparently already knowing she had been sexually assaulted. "There's not a minute that goes by that I don't think about what that family [of nurse Jacintha Saldanha] is going through and the thought that we may have contributed to it is gut-wrenching," she said. Glenarthur called on the radio station to take steps "to ensure that such an incident could never be repeated." The case has triggered demands for tougher regulation of the electronic media although Australia's press regulator, the Australian Communications and Media Authority, has not commented on whether the station broke any rules. In interviews on Australian television, the pair broke their silence following Saldanha's death last week in London, as 2Day FM's owner said it was cancelling their show and stopping all hoax calls by its broadcasters. Audio of the call posted online suggests a woman spoke briefly to the DJs before she put the call through early Tuesday morning to the ward where the Duchess of Cambridge was being treated for acute morning sickness. "[It was] the worst phone call I've ever had in my life," Greig told the Nine network's A Current Affair programme. "You can tell by reading the article that she just hates us and has always hated us. A call that would go for 30 seconds that we thought we would be hung up on," said Christian. Both said they did not know what the vetting process included. A tweet from 2Day FM last week after the incident described it as a "hilarious prank." "We just hope that her family and friends are as good as they can be and that they are getting the love and support they deserve." "I know you will say it is harmless fun, the management of 2DayFM will say that it won't happen again, but this is exactly where the phone hacking scandal started." Holleran reiterated that he was "deeply saddened" by the tragic events that had unfolded since the call but again said no one could have reasonably foreseen the circumstances. Rhys Holleran, CEO of Southern Cross Austereo, which owns 2Day FM, said the station attempted to contact King Edward VII hospital "no less than five times" before broadcasting the pre-recorded material. A St. James's Palace spokesman said: "The Duke and Duchess of Cambridge are deeply saddened to learn of the death. On the contrary, we offered our full and heartfelt support to the nurses involved and hospital staff at all times."
– Australian DJs Michael Christian and Mel Greig have broken their silence on their royal prank call gone horribly wrong, reports the Guardian, tearfully telling an interviewer that they're "shattered, gutted, heartbroken" over the death of nurse Jacintha Saldanha. "No one could've imagined this to happen," Christian said. "Naturally, we're shattered. We're people, too." "There's not a minute that goes by that I don't think about what (Saldanha's) family is going through, and the thought that we may have contributed to it is gut-wrenching," says Greig. The DJs meant no harm, adds Christian: "At every single point it was innocent on our behalf." Innocent or not, Greig and Christian "will not return to the airwaves until further notice," says parent company Southern Cross Austereo, which has also axed their show, halted all prank calls, and nixed ads amid an internal review, CNN reports. But the station is doubling down on its decision to air the prank, saying that it had tried to contact King Edward VII's Hospital no fewer than five times to talk about the recording before airing it. "It is absolutely true to say that we actually did attempt to contact those people on multiple occasions," says Southern Cross' CEO. It's not clear if the hospital responded, notes the AFP, but it has mounted a withering assault against the station in the aftermath of Saldanha's death.
