The UN Security Council unanimously passed Resolution 1530 condemning the bombings. This happened early in the day and, at the request of the Spanish government, the resolution accused ETA unambiguously of being responsible. The resolution condemns in the strongest terms the bomb attack in Madrid, Spain, perpetrated by the terrorist group ETA. After al-Qaeda involvement became clear, Germany and Russia voiced their concern over Spain's hasty assurances and suggested adding the word "allegedly" to the statement. On 15 March, Spain's ambassador to the UN Inocencio Arias submitted an unapologetic letter updating the Security Council on the progress of the investigation, repeating that the Spanish government had the strong conviction that ETA was involved. UN Secretary General Kofi Annan said that:""I think there is a lesson here for everybody, including the council members"".
