United Nations Security Council Resolution 2166

United Nations Security Council Resolution 2166, concerning the shootdown of Malaysia Airlines Flight 17, was sponsored by Australia and adopted unanimously on 21 July 2014. The resolution expressed support for the "efforts to establish a full, thorough and independent international investigation into the incident in accordance with international civil aviation guidelines" and called on all United Nations member states "to provide any requested assistance to civil and criminal investigations".

Preparation
The resolution was drafted on 18 July, put into circulation on 19 July and agreed the next day. Russia, a permanent member with a veto right, supported the resolution after negotiations led to some text changes, including terming the incident as "downing" of the aircraft instead of "shooting down".
