An investigation is underway outside the Russian Embassy after a suspicious package was delivered to the Griffith site, as of lunchtime Thursday.
ACT Policing and emergency services were called to the embassy shortly after 10am following a report an unknown package had been found. The package is believed to contain an unknown white powder.
Police scientists were still analysing the substance mid-afternoon.
Police in hazmat suits had cornered off the area surrounding the embassy and were directing the public away.
Four large yellow emergency trucks with flashing blue and red lights were parked outside the embassy as investigations continued inside. In the central reservation, there was a host of police and ACT ambulance vehicles.
Canberra Avenue has been reduced to one lane of traffic heading out of the city towards Manuka.
ACT police advised that the contents of the package were being assessed.
More to come.
