During a state visit to France in 1934, the king was assassinated by an agent of the Croatian terrorist organization, the Ustasa.

So they do not mention VMRO on this occasion.

On account of the deaths of three members of his family on a Tuesday, Alexander refused to undertake any public functions on that day. On Tuesday 9 October 1934 he had no choice, as he was arriving in Marseille to start a state visit to the Third French Republic, to strengthen the defensive alliance against Nazi Germany. When being driven in a car through the streets along with French Foreign Minister Louis Barthou, a gunman, Vlada Georgieff, stepped from the street and shot the King, the Minister and the chauffeur.
... The assassin Vlada Georgieff -- driver of the leader of the Internal Macedonian Revolutionary Organization, Ivan Mihailov -- was cut down by the sword of a mounted French policeman, then beaten by the crowd. By the time he was removed from the scene, he was already dead.

And here about VMRO:

http://en.wikipedia.org/wiki/Internal_Macedonian_Revolutionary_Organization
The Internal Macedonian Revolutionary Organization (in Macedonian: Vnatrešna Makedonska Revolucionerna Organizacija, Внатрешна Македонска Револуционерна Организација, in Bulgarian: Vatreshna Makedonska Revolyutsionna Organizatsiya, Вътрешна македонска революционна организация, ВМРО), commonly known in English as IMRO, was the name of a revolutionary political organization in the Macedonia and Thrace regions of the Ottoman Empire, as well as in Bulgaria, and after 1913 in the Macedonian regions of Greece and Yugoslavia. In the 1990s it was revived as a nationalist political party in both the Republic of Macedonia and Bulgaria.

VMRO
Flag with initials used on it. The Bulgarian/Macedonian name that sounds something like "Vnutrashnya Makedonska Revolucionarna Organizacija". BMRO fought primarily against Turks for the independence of Bulgaria and Macedonia, and as might be seen from the flag, the ideology was anarchic-revolutionary (as were the methods). The group was soon (at the beginning of the 20th century) split between those wanting Macedonia a part of Bulgaria and those struggling for the independence of Macedonia. Therefore, to cut the story short, today we have VMRO both in modern Bulgaria and Macedonia (where it is called VMRO-DPMNE), both being modern democratic parties that have long forsaken their anarcho-revolutionary methods.
