Ukrainian military drones targeted the port in Rostov-on-Don, Russia, overnight Sunday into Monday, according to a statement by Ukrainian President Volodymyr Zelensky on Telegram.
The strike marks another escalation in the campaign against Russian logistics infrastructure, hitting a critical node for grain and cargo exports in the southern region.
The development intensifies concerns over the security of Black Sea shipping lanes.
Rostov-on-Don serves as a primary inland hub for goods moving to and from the sea, and disruptions there can ripple through regional freight networks.
Markets are monitoring the incident for signs of broader route closures or insurance premium spikes, which have been recurring themes since the conflict began.
This attack follows a pattern of intensified Ukrainian drone operations against Russian port facilities.
