“Two Sydney brothers have now been found guilty of plotting to blow up an Etihad plane with a bomb hidden in a meat grinder and to carry out a lethal poisonous gas attack. The siblings plotted with their older brother, Tarek Khayat, who was involved with Islamic State in Syria, and 'the controller', an unidentified person connected with the older brother, according to the prosecutor Lincoln Crowley QC. Khaled Khayat, 51, was found guilty in May of conspiring, between mid-January and late-July 2017, to prepare or plan a terrorist act, but the NSW Supreme Court jury failed to agree on a verdict for his brother. Mahmoud Khayat, 34, faced a retrial and another jury found him guilty of the same charge on Thursday afternoon. Their motivation was said to have included supporting violent jihad and they were accused of doing many preparatory acts during the seven-month conspiracy. The plane plot involved a bomb in a meat grinder being put into the luggage of a fourth brother, Amer Khayat, who was flying out of Sydney on an Etihad flight, Mr Crowley told the first trial. Amer Khayat has been cleared of involvement in the plot. But the plan was abandoned because the baggage was found to be overweight at the airport. Khaled Khayat then proposed that he himself would arrange to take the bomb, Mr Crowley said. 'The controller told him not to do that because he had to stay for the continuation of the work here and had to find someone else,' he said. The second plot involved poisonous gas which the older brother was going to make at his home following instructions given by the controller. When Khaled Khayat was arrested police found a piece of paper in his wallet that had Arabic words, numbers and symbols written on it. The paper was examined by a forensic chemist and Arabic interpreters, who determined that one side of the paper included the correct chemical equation for poisonous gas, while the other side had further details relating to the gas.”
