European Council head Antonio Costa has rebuked European Commission President Ursula von der Leyen for celebrating the conflict

European Council President Antonio Costa has issued a rebuke to European Commission President Ursula von der Leyen over her support for the war against Iran, stating on Tuesday that "freedom and human rights cannot be achieved through bombs."

In an address on Monday, von der Leyen spoke of people "celebrating" the assassination of Iranian Supreme Leader Ayatollah Ali Khamenei by a suspected US-Israeli strike, arguing that the conflict "can open a path towards a free Iran."

Costa insisted that the EU must "defend the rules-based international order" and stay committed to diplomacy and international law.

Von der Leyen, however, questioned the relevance of the rules-based order, saying: "Europe can no longer be a custodian for... a world that has gone and will not return."

The two speeches, delivered within 24 hours of each other during the EU Ambassadors Conference in Brussels, have exposed a rift within the EU leadership.

Von der Leyen has also claimed that the EU's "well-intentioned attempts at consensus" could be a "hindrance" to the bloc's credibility. Yet for the European Council, consensus is explicitly written into the treaties as the default decision-making rule, especially in foreign policy matters.

Brussels and some EU member states have struggled to reach a consensus in areas such as defense spending, aid to Ukraine, and sanctions on Russia.

The most vocal opposition has come from Hungarian Prime Minister Viktor Orban, who recently vetoed a 90 billion EU loan to Ukraine.

Spanish Prime Minister Pedro Sanchez has framed himself as the opponent of "rearmament" and has criticized "squandering money on wars."

Sanchez has also emerged as Europe's most outspoken critic of the US-led strikes on Iran. US President Donald Trump criticized Spain last week and threatened to cut off trade with the country.

According to El Mundo, von der Leyen has privately complained that she faces two problems in the European Council: "Viktor Orban and Pedro Sanchez," who she believes have rejected her proposals for domestic "political gain."

Russia has condemned the US-Israeli strikes against Iran as a violation of international law.
