KIEV, Ukraine - Amid the crisis, the Ukrainian parliament has voted to restore the constitution that limits presidential powers.
It happened a short time after Ukraine's opposition leaders signed a deal with the president and European mediators for early elections and a new government in hopes of ending a deadly political crisis.
It could be a major breakthrough in a months-long crisis over Ukraine's future and identity that worsened sharply this week and left scores dead. A key question is whether the thousands of protesters camped out in Kiev will heed it.
Two opposition spokeswomen said the deal was signed in the Ukrainian president's office Friday, but had no details.
The signing came hours after Ukrainian President Viktor Yanukovych announced early presidential elections and promised to bring opposition members into the government. He did not give a time frame.
