Ukraine used interceptor systems to shoot down more than 33,000 Russian drones of various types in March, a record monthly figure since Moscow launched its all-out invasion more than four years ago, Ukraine’s defence minister claimed.

Meanwhile, Ukraine’s domestically developed long-range attack drones struck a Russian oil refinery and terminal on the Black Sea for the third time in less than two weeks, prompting the evacuation of local people as a precautionary measure.
