European Union foreign policy chief Kaja Kallas said on Monday that it was "not nice" that Russian President Vladimir Putin might travel to EU member Hungary for talks on the war in Ukraine.

Hungary's Prime Minister Viktor Orbán has celebrated his country's role as the host for upcoming talks between U.S. President Donald Trump and Russia's Vladimir Putin.

"I cannot guarantee that an independent Polish court won't order the government to escort such an aircraft down to hand (Putin) over to the court in The Hague," Polish Foreign Minister Radoslaw Sikorski said.

Hungary's strongman leader Viktor Orbán calls Trump's announcement of a meeting with Putin in his country great news for "peace-loving people."

Vladimir Putin should only be allowed to travel to the European Union if he agrees to an unconditional ceasefire, France has said.

Questions loom about whether the Russian president might be subject to arrest while traversing the airspace of International Criminal Court members.

President Donald Trump has announced plans to meet with Russia's Vladimir Putin to discuss ending the war in Ukraine.

Hungarian Foreign Minister Peter Szijjarto has denied rumors that Budapest plans to block the European Union's 19th package of sanctions against Russia in light of the upcoming meeting between U.S. President Donald Trump and Russian leader Vladimir Putin.

Vladimir Putin will be allowed safe passage through Bulgarian airspace to attend peace talks with Donald Trump in Hungary.
