SYDNEY (AP) — They say they expected a hang-up and a few laughs. Instead, the Australian DJs behind a hoax phone call to the London hospital where the pregnant Duchess of Cambridge was being treated were deeply apologetic Monday as they described how their joke ended up going too far.

The phone call — in which they impersonated Queen Elizabeth II and Prince Charles — went through, and their station broadcast and even trumpeted the confidential information received. Whatever pride there had been over the hoax was obliterated by worldwide public outrage after Friday’s death of Jacintha Saldanha, the first nurse they talked to.
