The Intelligence and Security Service of the Moldova Republic (SIS) denied allegations saying it is responsible for organizing the violent acts on Tuesday and said that all similar statements, "usually made by Romanian citizens", are "an attempt to mislead the populace by intoxicating the information environment, in order to hide the true instigators". SIS claims that the violent acts were conducted "from the shadow" by foreign forces and promises "to watch over the country".

SIS expressed its concern over the "consistent attempts to influence the international opinion made by Romanian media and all media serving similar interests, for this purpose instigating the Moldova citizens, especially those who study in Romania".

The service also says that there was a "failed scenario" to violently change the Constitutional order, seen in the actions aiming attacking over the Parliament and the Presidency buildings, the profanation of the Moldovan flag and the hoisting of another state's flag.
