DUBAI, United Arab Emirates (AP) — Incendiary statements about Iran and Israel posted on Qatar's state-run news agency that authorities blamed on hackers sparked a regional dispute Wednesday, with the United Arab Emirates and Saudi Arabia blocking Qatari media including Al-Jazeera. Online footage of Qatari state television's nightly newscast from Tuesday showed clips of Sheikh Tamim at the ceremony with the anchor not mentioning the comments, though a scrolling ticker at the bottom of the screen had the alleged fake remarks. The hackers also purportedly took over the news agency's Twitter feed and posted alleged quotes from Qatar's foreign minister accusing Arab nations of fomenting a plot against his country. Sheikh Saif Bin Ahmed Al Thani, the director of the Qatari government's communications office, issued a statement saying authorities had launched an investigation. In 2012, a damaging virus crippled computer systems at Qatari natural gas producer RasGas soon after a similar attack on Saudi Arabia's state-run oil company. By early Wednesday morning, those living in the UAE and subscribers to local cable providers couldn't access the channels of Al-Jazeera, the pan-Arab satellite broadcaster based in the Qatari capital, Doha.
