On Tuesday, Russia’s defense ministry announced it is pulling some troops from the Ukraine border. The reports said that some troops will be pulled once they have completed their exercises.

However, Ukrainian officials remain skeptical over the reports.

The Hill reports:

“Russia constantly makes various statements,” Ukrainian Foreign Minister Dmytro Kuleba said, according to The Associated Press. “That’s why we have the rule: We won’t believe when we hear, we’ll believe when we see. When we see troops pulling out, we’ll believe in de-escalation.”

Russia did not specify how many of the over 130,000 troops it has amassed along the border with Ukraine would be pulled back. The announcement also made no mention of the Russian troops conducting military drills in Belarus that are scheduled to continue through Feb. 20.

Meanwhile, Russian Foreign Minister Sergey Lavrov reportedly said that country’s drills were held “on its own territory and according to its own plans, they start, go on and end as planned” no matter ​​“who thinks what and who gets hysterical about it, who is deploying real informational terrorism.”

“We’ve always said the troops will return to their bases after the exercises are over. This is the case this time as well,” Dmitry Peskov, a spokesperson for the Kremlin, added, according to Reuters.

Hours before the Tuesday announcement a U.S. defense official said Russian troops were moving closer to the border with Ukraine.
