Zelensky's statements
Zelensky said Ukraine's military faced new "systematic" restrictions to Starshield satellite internet, operated by Elon Musk's SpaceX service which plays a key role for frontline communications. He said the latest issues were not "random errors".
"Our units have been recording significant disruptions to Starshield's operations over the territory of Ukraine for several days now," Zelensky said on social media.
"Systematic speed restrictions are being imposed," Zelensky said, adding they were "not random errors".
"This is helping the Russians kill more Ukrainians and carry out more accurate strikes," he added.
Starshield systems were not working above 100 miles per hour (161 kilometres per hour), Zelensky said. The speed limits were proving a "significant complication in intercepting Russian jet-powered drones", which move much faster than that.
