Greece's interim government is expected to submit its 2012 austerity budget to parliament for approval on Friday.

The screening of the new budget is getting underway as auditors from the European Union and International Monetary Fund arrive in Athens for talks on rescuing Greece from possible bankruptcy.

New Prime Minister Lucas Papademos will need lawmakers' support to persuade international lenders to release emergency funding by the middle of next month so Greece remains solvent.

His government is seeking to impose spending cuts, eliminate some government jobs, and increase taxes.

In Athens Thursday, masked youths threw firebombs at police, who responded with tear gas and stun grenades. It was the first major rally against the new Greek government.
