U.S. Secretary of State Antony Blinken has agreed to meet with his Russian counterpart Foreign Minister Sergey Lavrov this week provided Russia does not invade Ukraine, amid a push to de-escalate tensions through diplomacy.

On Sunday, President Biden similarly agreed to meet with Russian President Vladimir Putin “in principle” on the condition that the Russian leader not proceed with an invasion of Ukraine.

Other reports reveal that a U.S official warned the United Nations that Russia has lists of Ukrainian individuals “to be killed or sent to camps following a military occupation.”

Fox News reports:

Bathsheba Crocker, U.S. ambassador to the United Nations, sent a letter to the U.N. human rights chief, The Washington Post reported Sunday.

“I would like to bring to your attention disturbing information recently obtained by the United States that indicates that human rights violations and abuses in the aftermath of a further invasion are being planned,” Crocker wrote. “These acts, which in past Russian operations have included targeted killings, kidnappings/forced disappearances, unjust detentions, and the use of torture, would likely target those who oppose Russian actions, including Russian and Belarusian dissidents in exile in Ukraine, journalists and anti-corruption activists, and vulnerable populations such as religious and ethnic minorities and LGBTQI+ persons.”

“Specifically, we have credible information that indicates Russian forces are creating lists of identified Ukrainians to be killed or sent to camps following a military occupation,” she warned. “We also have credible information that Russian forces will likely use lethal measures to disperse peaceful protests or otherwise counter peaceful exercises of perceived resistance from civilian populations.”
