The United States denied Moscow’s claim Saturday that an American submarine was conducting operations in Russian territorial waters, breaking international law as tensions are high amid a possible invasion of Ukraine

"There is no truth to the Russian claims of our operations in their territorial waters," U.S. Navy Capt. Kyle Raines, a spokesperson for the U.S. Indo-Pacific Command, said, according to Reuters. "I will not comment on the precise location of our submarines but we do fly, sail, and operate safely in international waters." 

Vladimir Putin’s government claimed the submarine ignored commands from the Russian navy via sonar to surface near the Kuril Islands in the Pacific Ocean early Saturday, forcing it to chase the U.S. vessel away using unnamed "appropriate means," the Navy Times reported.
