Amidst fears that Russia is invading Ukraine, and in a move that Washington is seeking to show it stands by the allies, the Pentagon said, President Joe Biden has decided to deploy more troops to Europe.

Pentagon spokesman John Kirby explained that the United States would take all measures "to protect our forces and our allies."

Kirby added that the deployment of more American troops would include Poland, Germany and Romania, and Washington welcomed France's announcement of its intention to deploy troops to Romania.

The West fears that Russia will invade Ukraine, while Moscow is showing security concerns that Kiev may join NATO, saying it wants "security guarantees."

Some 2,000 troops will be sent from Fort Bragg Base, North Carolina, to Poland and Germany, while another 1,000 troops stationed in Germany will be transferred to Romania, according to media reports citing American officials.

In his first direct statements about the crisis in nearly six weeks, Putin showed no sign of backing away from security demands, which the West described as impossible and a possible pretext for an invasion of Ukraine, which Moscow denies.

Recent satellite photos have shown military reinforcements of the Russian army in both Crimea and the east of the country, while tensions are growing with the West, due to fears that Russia will invade Ukraine.

In the meantime, recent satellite photos showed military reinforcements of the Russian army in both Crimea and the east of the country.

It should be noted that these images, published on Wednesday, are the first of their kind, since the outbreak of tension months ago, amidst a Western warning against Russia's invasion of Ukraine.
