Authorities in occupied Crimea, the Black Sea peninsula that Russia annexed illegally from Ukraine in 2014, declared a state of emergency Friday following weeks of punishing Ukrainian drone strikes.

The Russian Defense Ministry said its air defenses intercepted 660 Ukrainian drones overnight across 13 regions, including Crimea. The peninsula, which Ukrainian President Volodymyr Zelensky has vowed to reclaim, has become the centerpiece of Kyiv’s campaign to demonstrate the reach of its increasingly advancing medium-range drone capabilities.
