Brazil plot and Merrylands car attack of police station

The federal police in Brazil say they've arrested 10 members of a suspected terrorist cell, just weeks out from the start of the Olympic Games in Rio de Janeiro. Meanwhile, New South Wales police are still investigating why a man set his car alight in the driveway of the Merrylands police station in Sydney west last night while the Prime Minister Malcolm Turnbull has asked his top counter-terrorism adviser to review Australia's response to the threat of so-called 'lone wolf' attacks.
