Other than the US getting called out in front of Russia and China in front of the UN Security Council:

    On 9 December 2011, Iran lodged a formal complaint to the United Nations Security Council over the UAV violating its airspace.

    Iran's U.N. ambassador stated in the letter that "My government emphasizes that this blatant and unprovoked air violation by the United States government is tantamount to an act of hostility against the Islamic Republic of Iran in clear contravention of international law, in particular, the basic tenets of the United Nations Charter."
