A US P-8A Poseidon plane, fitted to detect ships and submarines, has been detected flying along the Syrian coast by several aviation enthusiasts keeping an eye on flight radars on January 30. The plane made several passes along the Syrian maritime border flying at an altitude of 4.7km and then returned to its base in Sicily.
A similar P-8A Poseidon spy plane was seen near the Syrian coast on 15 December 2018 and even earlier on 8 December 2018.
