Residents of 16 villages in Tulcea county are receiving alert texts on their mobile phones warning of the fall of possible drone parts as a result of Russian strikes on Ukraine’s river ports. The most recent such warnings were issued on Sunday evening in the north of the county as groups of Russian drones were detected heading for Ukraine, the Romanian defence ministry said. The governor of Odessa region Oleh Kiper said Ismail district, home to a Danube port of the same name and used for the export of Ukrainian cereals, was again the target of Russian drone strikes. He said 11 drones were destroyed, but did not give details about possible damage to the port’s infrastructure.
