Editor's note: This is a developing story and is being updated.

Keith Kellogg, U.S. President Donald Trump's special envoy for Ukraine, arrived in Kyiv on Feb. 19.

Upon his arrival, the U.S. officials said his mission is mainly to "listen" and relay his findings to the White House.

"We understand the need for security guarantees. We understand... the importance of the sovereignty of this nation," Kellogg said.

Kellogg is visiting Kyiv shortly after the U.S. and Russian delegations held talks - without Ukraine's participation-  in Saudi Arabia on ending the war.
