National Security Analyst Morgan Ortagus said Tuesday on The Daily Briefing that alleged attacks on U.S. diplomats in Cuba and China has taken harassment to "incredibly scary" levels.

NBC News reported that Russia is the "main suspect" behind unexplained attacks, which left individuals with brain injuries, loss of hearing loss and other cognitive issues.

The outlet also reported that the alleged incidents led to the removal of most of the diplomats from Cuba.

"What has happened in Cuba has really taken the harassment to a level that's incredibly scary," Ortagus said.

The alleged incidents began in late 2016 and are currently not conclusive enough to blame formally Russia.

As NBC News reported:

"The U.S. has said 26 government workers were injured in unexplained attacks at their homes and hotels in Havana starting in late 2016, causing brain injuries, hearing loss and problems with cognition, balance, vision and hearing problems. Strange sounds heard by the workers initially led investigators to suspect a sonic weapon, but the FBI later determined sound waves by themselves couldn't have caused the injuries."

According to U.S. officials, intercepted communications back the suspicion that Russia was behind the attacks.

"This goes back to a pattern of behavior of Russians harassing our diplomats," Ortagus said. "You assume that there are nefarious countries that are going to go after you, that are going to target and collect against you."
