I read in the Bulgarian media that this is the eighth incident for NATO with Ukrainian shells since the beginning of the war - at least 11 dead.
Automatic translation:
On 15 November, a Ukrainian air defence system fired a missile during a Russian wave of missile strikes against the country's infrastructure, which landed in Poland and caused the deaths of two people. However, this is the eighth such incident involving Ukraine since the start of the Russian military intervention on 24 February, in which a NATO member state was the victim. Here are the other 7:
1. 2 March - Ukrainian S-300 air defence system destroyed a Romanian MiG-21 fighter jet. The pilot died.
2. March 2 - Ukrainian air defense shot down a Romanian Mi-8 military transport helicopter that had flown out to search for a MiG-21 fighter shot down by Ukraine. The crew died (the standard crew of such a helicopter is three people).
3. 3 March - Estonian bulk carrier Helt is blown up by a Ukrainian sea mine off the coast of Odessa. 4 people are missing.
4. 10 March - A Ukrainian Tu-141 "Strizh" UAV crashes near Zagreb. Fortunately, there are no fatalities.
5. March 13 - Ukrainian territorial defense troops shot up the car of American New York Times journalist Brent Renaud near Irpen.
6. 9 September - A Romanian minesweeper was blown up by a Ukrainian naval mine near Constanta. Fortunately, there were no fatalities.
7. November 9 - A Turkish boat is blown up by a Ukrainian sea mine off the coast of Turkey. Fortunately there were no casualties.
