The Nagorno-Karabagh Crisis:A Blueprint for Resolution (PDF). Public International Law & Policy Group and the New EnglandCenter for International Law & Policy (June 2000). ციტატა: „In August 1919, the Karabagh National Council entered into a provisional treaty agreement with the Azerbaijani government. Despite signing the Agreement, the Azerbaijani government continuously violated the terms of the treaty. This culminated in March 1920 with the Azerbaijanis' massacre of Armenians in Karabagh's former capital, Shushi, in which it is estimated that more than 20,000 Armenians were killed.“

Zubov, Политическое будущее Кавказа: опыт ретроспективно-сравнительного анализа (Political future of the Caucasus),"Znamiya" journal, 2000, #4 "Британская администрация почему-то передала населенные армянами уезды Елизаветпольской губернии под юрисдикцию Азербайджана. Британский администратор Карабаха полковник Шательворт не препятствовал притеснениям армян, чинимым татарской администрацией губернатора Салтанова. Межнациональные трения завершились страшной резней, в которой погибла большая часть армян города Шуши. Бакинский парламент отказался даже осудить свершителей Шушинской резни, и в Карабахе вспыхнула война." "British administrator of Karabakh colonel Shuttleworth didn't impede the discrimination of Armenians by Tatarian administration of governor Saltanov. The national clashes ended by the terrible massacres in which the most of Armenians in Shusha town perished. The Parliament in Baku refused even condemn the accomplishers of the massacres in Shusha and the war was started in Karabakh."
