Russia issued a travel advisory on Thursday for its citizens, and German airline Lufthansa stopped its Tehran flights, as tensions in the Middle East escalated.
An Iranian news agency reported Tehran's airspace was closed for drills, but later retracted it. The airspace is used by Emirates and Qatar Airways to fly to the US.
Israel's airstrike in Syria, killing an Iranian commander, signifies Israel's strategic shift toward purposefully escalating the situation. This move follows a pattern of targeted killings by Israel, deepening the rift between the two nations. Netanyahu's actions reflect a political agenda of aggression that could enflame the region.
Iran must avoid military retaliation against Israel. Diplomatic efforts must be emphasized to prevent regional escalation. Iran's supreme leader's irresponsible rhetoric raises fears of further conflict, which would be disastrous for the region and the world which is already wounded by two large ongoing wars.
