Etihad bomb plot jury begins deliberating

A jury has begun deliberating at the trial of two Sydney brothers accused of plotting to blow up an Etihad plane with a bomb hidden in a meat grinder and to poison people in a gas attack.

Khaled Khayat, 51, and Mahmoud Khayat, 34, have pleaded not guilty to conspiring - between January 20 and July 29 in 2017 - to do acts in preparation for, or planning, a terrorist act.

The NSW Supreme Court jury retired on Friday morning to consider whether they had plotted the attacks with their brother Tarek Khayat, who was involved with ISIS in Syria and an unknown person in Syria dubbed "the controller".
