An Iranian drone hit a British military base in EU-member Cyprus in the early hours of Monday and another two were intercepted, prompting an evacuation of the facility and surrounding area.

A spokeswoman for the European Commission said the bloc had not discussed article 42 of the EU treaty -- which compels the bloc's 27 nations to assist fellow members in case of armed aggression -- following the strike.

But asked if Brussels was already preparing for the potential activation of the clause in the case of a further escalation, she said the matter was certain to come up soon.

"This question... is certainly going to be discussed in the coming days, in the various meetings that are foreseen," commission spokeswoman Paula Pinho told a press conference.

"For the moment no such discussion has taken place."

Commission chief Ursula von der Leyen stressed earlier that, while Cyprus was "not the target" of the drone attack, the EU was solidly behind its member states.

"We stand collectively, firmly and unequivocally with our Member States in the face of any threat," she wrote on X.

Cyprus currently holds the six-month rotating presidency of the EU.

An informal meeting of the bloc's European affairs ministers due to take place Monday and Tuesday in Cyprus was postponed to a later date following the strike.
