The Ukrainian S-300 missile that was fired Thursday by Ukrainian armed forces on Belarusian territory might be part of someone's plan, State Secretary of the Belarusian Security Council Alexander Volfovich told Sputnik on Friday.

"Kiev seeks to provoke a regional conflict by any means. It is not enough for Ukraine to have a war on its own territory. An example of this is the recent incident with the destruction of a Ukrainian S-300 missile. We will establish the reason for its fall on our territory, but the probability that it flew to us by accident is very low. Apparently, someone's plan is being realized here," Volfovich said.

He added that Warsaw showed reluctance to discuss regional security issues related to the fall of the missile in Belarus.

Following the incident, the Belarusian Foreign Ministry summoned Ihor Kyzym, the Ukrainian Ambassador to Minsk, and demanded a thorough investigation into the incident, Belarusian Foreign Ministry spokesman Anatoly Glaz said, adding that the Ministry asked to bring those responsible to justice and take comprehensive measures so that such events do not reoccur.

"As you know, the Belarusian air defense forces shot down a Ukrainian S-300 missile over the territory of Belarus today. This is a very serious incident. And Belarus takes this issue as seriously as possible. In this regard, the Belarusian Foreign Ministry summoned the Ukrainian Ambassador to Belarus Ihor Kyzym today and expressed its strong protest to him," Glaz told reporters.

Belarusian Foreign Ministry spokesman Anatoly Glaz said it is necessary to wait for the end of the investigation to determine if it was a case of deliberate provocation.

"An investigation is underway now. There is no exact information to date. An investigative team is working," Glazov said, answering a question about whether the incident was an act of provocation or just an accident.
