Ukraine denies targeting Bulgaria after drone explodes near gas pipeline.

Ukraine has denied any involvement in an incident in Bulgaria, where a drone exploded near a gas pipeline over the weekend. Bulgarian authorities said the drone appeared to be a type used by Ukraine’s military. The aircraft came down in a field near the Romanian border, close to the Black Sea. That area has seen an intensifying drone war between Russian and Ukrainian forces. Ukraine has not said what it believes the drone was doing there, but it firmly rejected claims that it had targeted Bulgarian territory.
