LIVE UPDATES: Ukraine Violated Agreements on Humanitarian Corridors, Russian Military Says

Ukrainian President Volodymyr Zelensky claims that all humanitarian corridors announced on Saturday in Ukraine worked out and thousands of people were able to take advantage of them.

"All the humanitarian corridors that were agreed upon, they worked. We managed to take out 12,729 people today. The humanitarian cargo for Mariupol should arrive tomorrow afternoon," Zelenskyy said in a video address.

Meanwhile, the head of the Russian National Defense Control Center, Mikhail Mizintsev, said on Saturday that Ukraine had rejected multiple attempts by Russia to conduct humanitarian evacuation of civilians from Mariupol to Russia.

The general accused Ukrainian troops of violating arrangements on humanitarian corridors and "hunting" those who try to flee eastward. Ukraine’s national security agency SBU has been tracking phone calls and conducting mass searches and arrests to stop people from going to Russia, Mizintse said.

Vucic also remarked during the Saturday interview that he would accept the price of $400 per 1,000 cubic meters of Russian natural gas after the delivery contract expires in June.

"Back when I was negotiating with [Russian President Vladimir] Putin I did not agree to the price of $400 per 1,000 cubic meters. I would have signed up to it now by both hands," he told TV Pink.

Serbia has been paying Russia $270 per 1,000 cubic meters, with shipments of 6 million cubic meters a day contracted until June 1. Serbia hopes to negotiate a 10-year deal next.

More than 6,900 foreign nationals are being held by Ukrainian far-right forces to be used as a human shield, the head of the Russian National Defense Control Center said on Saturday.

"More than 6,900 citizens from 16 foreign countries are still being held hostage as a ‘human shield’ by Ukrainian neo-Nazis," Mikhail Mizintsev said.

Foreign crews of more than 50 foreign-flagged vessels have been stranded in Ukrainian seaports, the general added.

The foreigners hail from Azerbaijan, Greece, Georgia, Egypt, India, Lebanon, Syria, Turkey, the Philippines and Jamaica, among others. Russia is in contact with their respective diplomatic missions.

Plenkovic called for closer NATO cooperation earlier in the day after a Tu-141 spy drone dropped down in a parking lot after flying undetected through Romania and Hungary from Ukraine. No party to the conflict admitted to having launched it.

MOSCOW (Sputnik) - Russian warplanes and combat drones hit 79 assets of the Ukrainian military infrastructure on Saturday alone, a spokesperson for the Russian Defense Ministry said.

Maj. Gen. Igor Konashenkov said this included four command and communication units, two surface-to-air missile systems, three multiple rocket launchers, an electronic warfare target, six ammunition, fuel and lubricant depots, and 54 clusters of armored vehicles.

Russian planes and air defense systems downed a Ukrainian Mi-24 helicopter and three drones, including a Turkish combat drone Bayraktar.

Konashenkov estimated that 3,593 enemy assets had been destroyed since the special operation began in Ukraine more than two weeks ago.

MOSCOW (Sputnik) - Russian Prime Minister Mikhail Mishustin signed a decree on Saturday to resettle refugees from Ukraine and the Donetsk and Lugansk people’s republics across the country.

Regional authorities will accept people fleeing the conflict in Donbass within the agreed quotas, giving priority to relatives of Russian citizens and residents already living in those regions. The decree put the total number of refugees at 95,909.

Russian President Vladimir Putin officially recognized the Donetsk and Lugansk people's republics as independent states in a speech on February 21 and ordered a special operation to protect locals three days later.

The UN refugee agency estimated on Friday that almost 2.6 million had been displaced by fighting, with a majority fleeing to Poland and over 105,000 to Russia.
