The government of Ukraine, a nation roiled by massive protests in recent weeks, made major concessions Tuesday in an effort to quell the uprising that has gripped the capital Kiev and spread beyond it. Ukraine's prime minister resigned, and just hours later, the country's parliament voted to repeal new anti-protest laws.

"Normally, this resignation would be a good solution, but among the people there is zero trust in the government,” said the program director at a non-profit think tank in Ukraine.
