Protesters take to the streets of Athens

Greek lawmakers approved pension cuts and tax hikes on Thursday sought by the country's lenders to unlock vital financial aid, as angry demonstrators protested outside parliament over new austerity, the latest since the country plunged into crisis seven years ago.

The leftist-led government hopes that legislating the measures, four days before euro zone finance ministers meet in Brussels, will convince its lenders to release a 7.5 billion euro (6.44 billion pounds) bailout tranche and grant it further debt relief.
