After the United States threatened to launch an attack, placing Iran on alert, the European Union Aviation Safety Agency on the 16th advised airlines to avoid flying over Iranian airspace.
According to AFP, the EU Aviation Safety Agency stated: "In view of the ongoing situation and the possible military action by the United States, Iranian air defense forces are on high alert, and the risk of misjudgment is currently increased."
"The presence and potential use of various weapons and air defense systems, combined with the unpredictable responses of different countries and the possible activation of ground-to-air missile systems, pose a high risk to civilian flights operating at all altitudes and flight levels."
On December 28 last year, Iran erupted in protests related to the cost of living, which later evolved into one of the largest protest movements against the clerical leadership since the establishment of the Islamic Republic of Iran in 1979.
On the 15th, U.S. President Trump thanked the Iranian government for cancelling "all scheduled executions." He had previously issued a warning to the authorities in Tehran that continued crackdowns would lead to "serious consequences."
