Foreign mediators have returned to Ukraine for a new round of talks with the two rivals in the country's ongoing election dispute. The presidents of Poland and Lithuania are among those in Ukraine's capital, Kiev, where opposition protesters are again blocking government buildings.
The mediators arrived in Kiev as supporters of opposition candidate Viktor Yushchenko decided to block access government buildings, once again.
Mr. Yushchenko had called off that pressure tactic, early Tuesday.
The European Union's foreign policy chief, Javier Solana, joins the presidents of Poland and Lithuania in an attempt to resolve the ongoing political crisis which has gripped Ukraine for more than a week.
Russia is also expected to take part, despite a warning from Russian President Vladimir Putin against "foreign pressure" in defusing the crisis.
Russia strongly backs Prime Minister Viktor Yanukovych, who was declared the winner of the November 21 runoff election despite evidence of fraud that led to the crisis.
Holding a new election is one of the options being considered, amid increasing calls from the world community to keep the protests peaceful and to use only legal means to end the crisis.
