Thousands protest across India against currency policy

Indian Prime Minister Narendra Modi, in his Nov. 8 televised address, announced the demonetization of India's 500 and 1,000-rupee notes, which made up 86 percent of the country's currency. He said it would wipe out rampant corruption, though in a country of 1.3 billion where most people don't have bank accounts, it also wiped out legally collected savings.

Thousands of people are demonstrating across India to protest the government's sudden decision to withdraw large-denomination currency from circulation, a move that has caused enormous hardship to millions of people in the country's predominantly cash-based economy.

But the response to Monday's "day of rage" called by opposition parties was patchy, with the protests only affecting daily life in opposition-ruled states.

Nearly three weeks ago, Prime Minister Narendra Modi announced that 500- and 1,000-rupee notes would become worthless overnight and would be replaced by new currency in a bid to stamp out corruption.

Opposition parties have criticized the move, saying the government mismanaged the currency change and that Modi should address Parliament to explain his decision.
