British Prime Minister David Cameron vowed to probe tabloid News of the World on phone hacking allegations, the BBC reported. He said claims that the Rupert Murdoch-owned paper broke into a murdered 13-year-old girl's cell phone and tampered with evidence were "disgusting." News of the World is also under investigation for hacking in the voice mail of victims and relatives of those who died in London's 2005 terrorist attacks. Celebrities and politicians, from Sienna Miller and former Deputy Prime Minister Lord Prescott, have also been allegedly targeted. Murdoch called the paper's conduct "deplorable," Reuters reported.
