DFAT to analyse Greek riots

Australian authorities will analyse the situation in Greece and change travel advisories if necessary, Prime Minister Kevin Rudd says.

Three people have died as a strike and riots shook the country, which is grappling with measures to avert national bankruptcy.

The victims died in a bank which caught fire after rioters threw Molotov cocktails inside. At least two other buildings - the Athens prefecture and one used by tax officials - caught fire in other firebomb attacks on the margins of the protests.

"The department of foreign affairs will be analysing the situation carefully and issuing any appropriate revisions to travel advisories," Mr Rudd told reporters in Whittlesea, north of Melbourne, where he was launching a national male health policy.

Advice would be taken from police and security authorities around the world. The department's travel advice for Greece has not changed since the crisis hit.

The advice warns that bombings have increased, and violent riots can break out with little warning. "You should avoid all protests and demonstrations as they may turn violent," the department cautions.
