Aussie police prepare to use sound cannons, ban eggs and snakes

Brisbane

AUSTRALIA is deploying its largest ever peacetime security operation amid fears of violent protests or extremist attacks when world leaders including US President Barack Obama converge on Brisbane for the G-20 summit this weekend.

More than 6,000 police officers from as far afield as New Zealand have locked down the centre of Australia's third-biggest city, while F/A18 Super Hornets will enforce a strict no-fly zone around the Brisbane Convention and Exhibition Centre.
