ATHENS, Greece — Greek lawmakers passed a deeply resented new austerity bill Thursday, caving in to the demands of international creditors in order to avoid a national bankruptcy. The austerity measures won 154-144 in the 300-member parliament despite dissent from a prominent Socialist lawmaker who voted against a key article of the bill. The vote was expected to pave the way for a vital $11 billion payout from creditors within weeks so Greece can stay solvent.

Unions kept the country’s services crippled on the second day of a general strike, in opposition to the new measures that include pay and staff cuts in the civil service as well as pension cuts and tax hikes for all Greeks.
