The drone that crashed in Zagreb is not Ukrainian, the Defence Minister's adviser Markiyan Lubkivsky said on Friday, according to the Interfax-Ukraine media outlet.

“The drone that crashed in the capital of Croatia does not belong to Ukraine,” Lubkivsky was quoted as saying.

“This drone did not have Ukrainian markings, it had red stars on it. This is not a Ukrainian drone,” Lubkivsky said on the air during a national telethon today.

He said that an unmanned aerial vehicle crashed in Zagreb at night and that the Croatian special services are currently studying this incident in cooperation with the Ukrainian Ministry of Defence, the General Staff of the Armed Forces of Ukraine and the Ministry of Foreign Affairs.

“We turned to our Croatian partners with a request to quickly and effectively investigate this incident in order to understand what kind of drone it is, who its manufacturer is and why it appeared in Zagreb,” said Lubkivsky, a former Ukrainian ambassador to Croatia.

The Hungarian air defence detected and tracked the drone that crossed its airspace on Thursday night before it crashed in Zagreb, the Hungarian Defence Ministry said today.

The air defence service of the Hungarian Armed Forces detected a flying object on its radars on Thursday night, the ministry said in a statement carried by the Hungarian MTI news agency.

The object was later identified as a TU-141 drone which has recently been used as a training target, the ministry said, adding that both the Ukrainian and Russian militaries had used such drones.

The drone had already been detected in Ukraine’s airspace, the Hungarian ministry said. Once it entered the Hungarian airspace, it was tracked by the air defence service until it exited the airspace, they added.

The TU-141 is a Soviet-era reconnaissance drone.
