The U.S. Navy has denied Russia's claim that it broke international law after Moscow said its naval vessel had to chase away a U.S. submarine from inside its territorial waters.

"There is no truth to the Russian claims of our operations in their territorial waters,” Indo-Pacific Command spokesman Navy Capt. Kyle Raines said in a statement published by Star & Stripes. “I will not comment on the precise location of our submarines, but we do fly, sail and operate safely in international waters," he added.

The Federal Bureau of Investigation and the Department of Homeland Security on Monday warned law enforcement, military and others charged with overseeing critical U.S. infrastructure to be prepared for potential Russian cyberattacks in conjunction with a possible invasion of Ukraine.

During a Monday afternoon conference call, the nation’s top cybersecurity officials briefed state and local government agencies and cybersecurity personnel, warning them to look out for signs of Russian activity on their networks. The federal officials also urged those on the call to dramatically lower their threshold for reporting suspicious activity.

A Russian invasion of Ukraine could begin at any time, the officials said, and the military action is also likely to be accompanied by cyberattacks targeting both Ukrainian and U.S. networks. Officials underscored that the U.S. believes Russia’s invasion of Ukraine is likely to begin with aerial bombings and missile attacks and in conjunction with cyber operations.

Two people who were on the call told Yahoo News that they were alarmed by how many people on the call appeared not to know the process for reporting suspicious cyberactivity.
