ATHENS, Greece - Greece's prime minister says he will reshuffle his Cabinet on Thursday and seek a vote of confidence for his new government in Parliament, after coalition talks with opposition parties failed.

The discussions came as anti-austerity riots hit central Athens. Prime Minister George Papandreou has struggled against falling approval ratings and an internal party revolt among the governing Socialists over a new package of austerity measures.

The measures must be passed by Parliament before the end of the month if debt-ridden Greece can continue receiving funding from its international bailout.
