Drone Likely From Ukraine Explodes in Bulgaria Near Gas PipelineSOFIA, Bulgaria (AP) — A drone entered Bulgarian airspace on Saturday and exploded close to an international gas pipeline shortly after crossing the border from Romania. A Ukrainian foreign ministry spokesperson said the Ukrainian military was looking into the incident but that it did not deliberately target Bulgaria. Heorhii Tykhyi said on Saturday that Ukraine and Bulgaria were in “close contact” to establish the circumstances of the incident. Bulgaria’s Prime Minister Rumen Radev said the drone exploded just after 5 a.m. about 100 meters (109 yards) inside Bulgarian territory. Following this incident, we will also redeploy border police anti-drone detection and countermeasure capabilities from the border with Turkey to the border with Romania,” Radev said.
