Authorities in Sydney have seized material that could be used to make an improvised bomb, as investigations continue into an alleged terror plot to bring down a plane.
Prime Minister Malcolm Turnbull this morning confirmed raids carried out in Sydney yesterday “disrupted” what appeared to be an “elaborate” conspiracy, and said extra security was in place at airports around the country.
Four men were arrested after the raids at five properties in the inner-city suburb of Surry Hills, and the south-western suburbs of Lakemba, Wiley Park and Punchbowl.
The ABC has been told police found items that could be used to make a homemade bomb when they raided the house at Surry Hills.
It is understood that authorities believe the group was intending to smuggle the device onto a plane in order to blow it up.
t is also understood the alleged cell was capable of making an improvised explosive device, but sources say it is unclear whether they would have succeeded in getting it onto a plane.
“We do believe it is Islamic-inspired terrorism. Exactly what is behind this is something that we will need to investigate fully,” AFP commissioner Andrew Colvin said.
Police do not yet know what type of plane the group planned to target or what timeframe they had for carrying out the alleged plot.
Mr Turnbull said the “major counter-terrorism operation” was ongoing.
Some travellers have experienced delays today at airports across the country because of the extra security measures.
“Some of the measures will be obvious to the public, some will not be — those travelling should go about their business with confidence,” Mr Turnbull said.
“Travellers should arrive at terminals at least two hours before flights to allow ample time for screening. They should limit the amount of carry-on and checked baggage, as this will help to ensure that security screening is efficient.”
Virgin Airlines and its budget subsidiary Tigerair released a statement confirming the additional security measures and urging travellers not to be alarmed.
“As the measures place an additional burden on the screening system, it may take a little longer than usual to get through the process,” it said.
A Qantas Group spokesperson — representing Qantas and Jetstar — said it was working closely with the Government and airport partners to implement the measures.
“Australia has very strong safeguards in place at its airports; these changes are about making them even stronger,” the spokesperson said.
