In a letter to the UN Security Council, US Ambassador Kelly Craft said the United States also stands "ready to engage without preconditions in serious negotiations with Iran, with the goal of preventing further endangerment of international peace and security or escalation by the Iranian regime."
The killing of Soleimani in Baghdad on Friday was justified under Article 51 of the UN Charter, wrote Craft in the letter seen by Reuters, adding "the United States is prepared to take additional actions in the region as necessary to continue to protect US personnel and interests."
Under Article 51, countries are required to "immediately report" to the 15-member Security Council any measures taken in exercising the right of self-defense. The United States used Article 51 to justify taking action in Syria against Islamic State militants in 2014.
