Al-Jazeera says hackers have targeted the Qatar-based TV satellite channel for the second time in a week, sending out false news reports on its mobile sms service. Al Jazeera confirm the hack in a tweet,"We'd like to inform our subscribers that Aljazeera sms sevice is being compromised by pirates and they've sent fake news news with no basis"

“The story claiming that the Prime Minister (Sheikh Hamad bin Jassem) has been the target of an assassination attempt in the royal palace is completely false and was a result of hacking of the service,” the channel said in breaking news.

A pro-Damascus group known as the Syrian Electronic Army quickly claimed responsibility for the Sunday hack on Twitter. Social networks, including Twitter, quoted Al-Jazeera’s mobile service on Sunday as saying that Sheikh Hamad was targeted in an attack on the palace in Doha and that the wife of the emir, Sheikha Moza bint Nasser, was lightly wounded.

Hackers posted a pro-Syrian statement on Al-Jazeera's website last week. Hackers left images of the Syrian flag and Al-Jazeera's site with the word "Hack" emlazoned on it, and a message saying the hack was in "response to the hostile position of the channel towards Syria, its people and government."
