Separately, Reuters reported that Elon Musk’s Starlink systems used by Ukrainian military units were down for two and a half hours overnight, a senior commander said, part of a global issue that disrupted the satellite internet provider.

Starlink experienced one of its biggest international outages on Thursday when an internal software failure knocked tens of thousands of users offline, the agency reported.

The commander of Ukraine’s drone forces, Robert Brovdi, later said the incident had highlighted the risk of reliance on the systems, and called for communication and connectivity methods to be diversified.
