The office of Ukrainian President Volodymyr Zelensky said in a statement on Sunday that negotiations would be held at the Belarusian-Ukrainian border.

Zelensky agreed that a Ukrainian delegation would meet with President Putin's representatives without preconditions during a phone call with Alexander Lukashenko.

The meeting is going to take place on the Ukrainian-Belarusian border, near the Pripyat River, on Monday morning, according to the deputy interior minister.

Zelensky said that Alexander Lukashenko would make sure all planes, helicopters, and missiles stationed on the territory remained on the ground.

Neither Russia nor Belarus have made any statements about the talks.

Zelensky said he would not meet the Russian delegation because of the invasion. He suggested other cities for the talks.

The Russian delegation is ready for talks, and we are waiting for the Ukrainians, according to the Kremlin.

Putin ordered his military command to put nuclear deterrence forces on high alert in response to Western sanctions.

Putin said in a meeting with his top officials on Sunday that NATO officials made aggressive statements about the country.

On February 24, Putin launched a full-scale invasion of Ukraine. Hundreds of civilian lives have been lost and it has drawn global condemnation. Insider's live blog is covering developments as they happen.
