Ukraine's government

The Russian Foreign Ministry has referred to the Bulgarian government as a "ruling regime," criticizing its handling of Victory Day commemorations and Europe Day events.

EU leaders will grapple with Hungary's Prime Minister Viktor Orban at a crunch summit meeting Thursday to try to overcome his veto on 50 billion euros in financial aid for Ukraine.

Day 673 of the invasion of Ukraine. Summary of key events in the last 24 hours:

Hungarian Prime Minister Viktor Orban on Dec. 15 blocked 50 billion euros ($55 billion) in EU aid for Ukraine, after leaders side-stepped his opposition to agree to open talks with Kiev on joining the bloc.

Ukraine's government is lobbying hard to be granted candidate status, and Kyiv finalised its application for EU accession in early May. The Council of the European Union is expected to decide on that issue at its June 23-24 summit.

Russian President Vladimir Putin's new warning to the West against sending longer-range rocket systems to Ukraine came as his forces claimed to have destroyed Western military supplies in their first such airstrikes on Ukraine's capital in more than a month.

Hopes for a weekend truce in Ukraine to celebrate the Orthodox Easter faded with talks between Moscow and Kyiv stalled as Russia said it aimed to take full control over the east and south of its neighbor.

Russia unleashed a wave of attacks on Ukraine targeting airfields and fuel facilities in what appeared to be the next phase of an invasion that has been slowed by fierce resistance. The U.S. and EU responded with weapons and ammunition for the outnumbered Ukrainians and powerful sanctions intended to further isolate Moscow.

Russian troops stormed toward Ukraine's capital on Feb. 26, and street fighting broke out as city officials urged residents to take shelter. The country's president refused an American offer to evacuate, insisting that he would stay. "The fight is here," he said.

The United States on Wednesday rejected Russia's key demand to bar Ukraine from NATO and said it believed Moscow was ready to invade but offered what it called a new "diplomatic path" out of the crisis.
