The chorus of condemnation and outrage from across the European Union swelled on Monday as leaders began discussing possible penalties they could direct at Belarus for its forcing down of a civilian passenger jet.
The actions at their disposal are, however, somewhat limited, given that there are already E.U. sanctions against Aleksandr G. Lukashenko, the brutal and erratic leader of Belarus who has clung to power despite huge protests against his government, and dozens of his immediate associates.
In a summit taking place Monday evening, European leaders were expected to discuss adding aviation-related sanctions.
The options may include designating Belarusian airspace unsafe for E.U. carriers, blocking flights from Belarus from landing in E.U. airports, and imposing sanctions against the national flag carrier, Belavia.
said that the government was responding to “unprecedented threats” from Belarus and that it would push for the European Union to impose further measures.
Prime Minister Kyriakos Mitsotakis of Greece, where the flight originated, said it was critical that the European Union take determined action, especially in light of the bloc’s frequent paralysis over foreign-affairs issues, including a recent failure to agree on a statement regarding the Middle East conflict.
“Our inability to reach a consensus on recent events in Israel and Gaza — where as a union we failed to present a unified stance — must not be repeated,” Mr. Mitsotakis told The Financial Times. “The forcible grounding of a commercial passenger aircraft in order to illegally detain a political opponent and journalist is utterly reprehensible and an unacceptable act of aggression that cannot be allowed to stand.”
