Egypt extends custody for Ausstralian journalist January 1, 2014 - 2:08AM Egyptian authorities have ordered an award-winning Australian journalist and two other reporters working for Al-Jazeera television to be detained for two weeks on suspicion of "disturbing public security," a judicial source says. Their arrests on Sunday came amid a widening crackdown on the Muslim Brotherhood of ousted president Mohamed Morsi, which the military-installed government declared a "terrorist" group last week. Al-Jazeera has identified them as Cairo bureau chief Mohamed Adel Fahmy - a dual Egyptian-Canadian citizen - Australian reporter Peter Greste and producer Baher Mohamed. Cameraman Mohamed Fawzi, who was also arrested on Sunday, has since been released. Prosecutors accused the film crew of "working in violation of the law, filming sovereign institutions, and airing videos aimed at disturbing peace and public security," the source said on Tuesday. The custody order can be extended. The reporters were also accused of having maps of Egyptian military installations on their laptops and of working for the channel despite its licence being cancelled by the authorities, the sources added. The four were arrested on Sunday in their office in a Cairo hotel. Greste, a former BBC journalist, won the prestigious Peabody award in 2011 for a documentary on Somalia. Qatar, which hosts and funds Al-Jazeera was a big supporter of Morsi before his overthrow by the army in July last year. To the fury of the military-installed interim government, it has been an outspoken critic ever since.
