On 16 March, Angola lodged a formal complaint with the UN Security Council concerning the violation of its borders and airspace as a result of Operation Rekstok. United Nations Security Council Resolution 447 was passed in response. The resolution "condemned strongly the racist regime of South Africa for its premeditated, persistent, and sustained armed invasions of the People's Republic of Angola, which constitute a flagrant violation of the sovereignty and territorial integrity of the country as well as a serious threat to international peace and security". A UN commission of inquiry logged 415 border violations by the SADF in 1979, an increase of 419% since the previous year. It also made note of 89 other incidents, which were mostly airspace violations or artillery bombardments that struck targets on Angolan soil.
