As Rolitico writes , citing reports from officials familiar with the investigation, there is no concrete evidence of the GRU's involvement in such attacks. But all American intelligence agencies are involved in the investigation, trying to prove it. Earlier, American diplomats complained of tinnitus, pressure, dizziness - these symptoms were called "Havana syndrome".
US intelligence services assure that only the GRU has the technology to carry out such attacks.
"It looks, smells and feels like the GRU", - said one of the interlocutors of the publication.
Other sources did not rule out that there are similar developments in Israel and China, but their intelligence did not work where the "Havana syndrome" manifested itself, while the interlocutors assured that such attacks took place in Europe, Miami, Northern Virginia and Washington.
Earlier it was reported that the former CIA agent claimed to be the victim of some secret weapon "with microwave radiation" developed and used by Russia. The attack, he said, was carried out when he arrived in Moscow on a business trip in 2017. The same symptoms - dizziness, malaise, migraine, nausea - were described by US and Canadian diplomats working in Cuba, hence the name "Havana syndrome".
