A terror suspect in Australia tried to smuggle a bomb on to a plane by planting it on his unsuspecting brother, say Australian police.
The plan was one of two alleged terror plots recently uncovered by authorities, who made several arrests across Sydney on Saturday.
The suspects were allegedly aided by the so-called Islamic State (IS).
The other plot involved building and setting off a device that could release toxic gas in a public enclosed space.
Police said the plans had been “completely disrupted”.
