Indonesia, alongside 23 other Muslim-majority nations, issued a joint statement condemning Israel’s military assault on Iran and called for an immediate ceasefire to prevent further destabilization in the Middle East. 

The statement − released amid escalating hostilities and signed by foreign ministers from countries including Saudi Arabia, Türkiye, Egypt, Pakistan, and Malaysia − emphasized a unified stance against what they described as an unlawful violation of Iran’s sovereignty.

In a release issued by the Indonesian Ministry of Foreign Affairs on Thursday, June 19, 2025, the government reaffirmed its commitment to international law and peaceful conflict resolution.

“Indonesia and 23 countries strongly condemn Israel’s military aggression on the Islamic Republic of Iran, which constitutes a serious breach of international law and threatens to drag the entire region into further instability,” the statement read.

The joint declaration, coordinated under the auspices of the Organization of Islamic Cooperation (OIC), unequivocally “rejected and condemned Israel’s recent attacks on Iran since June 13, 2025,” and called upon the international community to demand an end to the hostilities.

Escalation threatens regional peace

The statement warned that the conflict risks spiraling into a full-scale war with grave consequences for global peace and stability. The signatory countries expressed their “great concern regarding this dangerous escalation” and urged all parties to exercise maximum restraint and return to diplomatic dialogue.

“We call for immediate de-escalation and a comprehensive ceasefire,” the document emphasized, adding that sustainable peace can only be achieved through “respect for sovereignty, good neighborliness, and adherence to the United Nations Charter.”

A major pillar of the joint statement was the urgent call for the establishment of a Middle East Zone Free of Nuclear Weapons and Other Weapons of Mass Destruction.

The foreign ministers reiterated their demand that all countries in the region join the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), without exception.

The group stressed the “paramount importance of refraining from targeting nuclear facilities under IAEA safeguards,” noting that such acts are “serious violations of international law and international humanitarian law, including the 1949 Geneva Conventions.”

Indonesia’s Foreign Ministry further noted that diplomatic efforts must take precedence over military actions. “Military measures will not bring a durable resolution. Diplomacy, multilateral engagement, and adherence to international norms remain the only viable pathways,” the Ministry declared in Jakarta.

Dialogue on Iran’s nuclear program

The ministers reaffirmed that only a “swift return to negotiations” regarding Iran’s nuclear program could yield a sustainable and peaceful solution. They condemned the use of military threats or strikes as counterproductive, and instead emphasized confidence-building and multilateral dialogue.

The joint statement warned against using the nuclear issue as a justification for aggression, stating that “military targeting of nuclear sites poses catastrophic risks and violates both IAEA statutes and global humanitarian law.”

Maritime security

Another critical point in the declaration was the call to protect freedom of navigation in international waters and prevent actions that might jeopardize maritime security. The ministers stressed the need to “refrain from undermining maritime security in accordance with international law.”

The joint message concluded with a resolute appeal: “The crisis in the Middle East cannot and must not be resolved through military means. We urge all parties to return to diplomacy and dialogue, in full respect of international law and the UN Charter.”

Signatories

The joint statement was endorsed by foreign ministers of Algeria, Bahrain, Brunei Darussalam, Chad, Comoros, Djibouti, Egypt, Gambia, Indonesia, Iraq, Jordan, Kuwait, Libya, Mauritania, Malaysia, Pakistan, Qatar, Saudi Arabia, Somalia, Sudan, Türkiye, Oman, and the United Arab Emirates.

This collective diplomatic step comes ahead of the OIC Emergency Ministerial Meeting scheduled in Istanbul on June 21, 2025 where further coordination and unified responses to the Iran–Israel conflict are expected.
