Ukraine war: Elon Musk's SpaceX firm stops Ukraine from using Starlink for drones control
Early in the war, Ukraine was given thousands of SpaceX Starlink dishes - which connect to satellites and help people stay connected to the internet.
But it is also said to have used the tech to target Russian positions - breaking policies set out by SpaceX.
A Ukrainian official said companies had to choose which "side" they were on.
They could join Ukraine and "the right to freedom", or pick Russia and "its 'right' to kill and seize territories", tweeted presidential adviser Mykhailo Podolyak.
At an event in Washington DC on Wednesday, SpaceX president Gwynne Shotwell explained that Starlink technology was "never meant to be weaponised".
She made reference to Ukraine's alleged use of Starlink to control drones, and stressed that the equipment had been provided for humanitarian use.
Unmanned aircraft have played an important role in the war, having been used by Kyiv to search out Russian troops, drop bombs and counter Moscow's own drone attacks.
Russia has been accused of attempting to jam Starlink signals by SpaceX founder Elon Musk.
Ms Shotwell confirmed that it was acceptable for the Ukrainian military for deploy Starlink technology "for comms", but said her intent was "never to have them use it for offensive purposes".
She said the company had taken steps to "limit" the abilities of the Ukrainian armed forces to use Starlink in an offensive way - without giving further details.
