The official representative of the Pentagon did not confirm reports about the presence of American volunteers in Ukraine.

None of the top American military leaders have communicated with their Russian counterparts since Russia’s invasion of Ukraine began nine days ago, the U.S. Defense Ministry said.

Pentagon spokesman John Kirby told reporters that U.S. Secretary of Defense Lloyd Austin and Chairman of the Joint Chiefs of Staff General Mark Milley did not communicate with their colleagues from the Kremlin.

Prior to the Russian invasion, both Austin and Milley were in contact with Russian military leaders.

In addition, as Kirby said, the United States did not notice any changes in the location of Russia’s nuclear forces after Russian President Vladimir Putin put them on high alert over the weekend.

“I cannot talk about the changes that we have noticed in the structure of the Russian strategic nuclear forces,” John Kirby said.

Kirby also commented on the launch of a direct line to prevent possible conflict situations between the United States and Russia. He said that the presence of the line is crucial because the Russian and Ukrainian air forces are fighting for control of the airspace over Ukraine, and NATO airspace may be affected.

According to Kirby, the Russian military is now attacking a city located near Odessa. The United States is now trying to understand what this could mean for Ukraine’s largest Black Sea port.

The Russian armored column is still trying to reach Kyiv: “The actions of the Ukrainians actually slowed down this convoy… and in some places they stopped him,” Kirby said, adding that Russia is suffering from its own “mistakes and stumbles.”

“The attack on the nuclear power plant (in Energodar) is extremely dangerous and could cause much more damage and destruction to residents of Ukraine and, possibly, residents of neighboring countries,” Kirby added, commenting on reports of the shelling of the Zaporozhye NPP.

A spokesman for the U.S. Defense Ministry could not confirm the statements of the Ukrainian Embassy in Washington that about 3 thousand American volunteers are currently fighting in the country.

“American troops are not going to fight in Ukraine, including in the skies over Ukraine,” a Pentagon spokesman said.

“Belarus is partly responsible for what is happening in Ukraine. It is obvious that they are involved in a war started by President Putin’s choice,” Kirby said, adding that there are still no signs that Belarusian troops are preparing to invade Ukraine.
