The embassy recommended they head to a shelter arranged for Thais in Amol city in Iran, or stay with relatives outside Teheran. They should avoid risk areas, military zones and stay clear of crowds
Meanwhile, the embassy moved to a temporary office at No.6, Soheiliyeh Road, Kordan, for the safety of its visitors.
It said the latest conflict between Iran and Israel, since June 13, had damaged important sites Teheran and other major cities, including places near the embassy.
The Ministry of Foreign Affairs said the embassy advised Thais to leave dangerous zones in Teheran to safe areas, or a shelter it had prepared, as soon as possible.
The ministry said the embassy had not recommended evacuation. It also said no Thais had expressed an intention to leave Iran. The embassy does, however, have a contingency evacuation plan.
