ATHENS, Greece - Protesters have clashed with police outside Greece's Parliament after lawmakers passed a new austerity bill that will secure vital loan aid for near-bankrupt Greece.

Riot police in Athens fired tear gas to drive off stone-throwing youths. Tens of thousands demonstrated Thursday, a day after extensive rioting marred a protest during a nationwide general strike against the new cutbacks.

Three people died Wednesday after getting trapped in a burning bank torched by rioters. Lawmakers approved the austerity bill in a 172-121 vote allowing Greece to tap into euro110 billion ($140 billion) in bailout loans from euro-zone countries and the International Monetary Fund.

Greeks have been outraged by the measures.
