- NATO's integrated air and missile defence tracked the flight path of an object which subsequently crashed in Zagreb, an official of NATO told the Croatian state news agency Hina on Friday.

“NATO’s integrated air and missile defence tracked the flight path of an object which subsequently crashed in Zagreb. The Croatian authorities have announced that they are investigating this incident,” a NATO spokesman, Daniele Riggio, said in his brief answer to Hina’s query.

According to some speculations, a Tu-141 “Strizh” reconnaissance drone is believed to have arrived in Croatia from Ukraine, flying across Romania’s and Hungary’s airspace.

Croatian Defence Minister Mario Banozic said earlier today that the drone had been detected by Croatian radars and that it had been under surveillance as soon as it entered Croatia’s airspace.

It crashed seven minutes after entering Croatia’s air space, and the fall happened shortly after 2300 hours.

President Zoran Milanovic said that radars in Croatia had detected the object which was in the Croatian airspace for a brief period. He also added that no alert information had been provided to Croatia.
