A colonel in the Greek Air Force has been arrested on suspicion of espionage on behalf of China, according to reports from Greek media. The 54-year-old man is described as a communications specialist with prior service at the Greek Air Force headquarters, where he had access to sensitive NATO information. His arrest followed suspicions that arose when he made a private trip to China without informing his workplace.

Reports indicate that the colonel admitted to authorities that he had been collaborating with Chinese intelligence after being recruited during a conference abroad. This revelation raises significant concerns regarding the security of sensitive military data and alliances, particularly regarding NATO, which highlights the increasing risk of espionage threats from foreign powers amid international tensions.

Additionally, at least two more individuals are reportedly under investigation in connection with this case, hinting at a potentially broader network of espionage within the military. This incident could strain Greece's diplomatic relations, particularly with NATO and Western allies who may be wary of infiltration by foreign intelligence agencies.
