Ukraine says there has been a restriction to the speed of SpaceX's Starlink internet network in the country.
Starlink – owned by Elon Musk – plays a vital part in the war between Ukraine and Russia, allowing Kyiv to guide drones to Russian targets and also protect itself.
Elon Musk has suggested the US government may be behind the restriction on the speed at which some of Ukraine's weapons can travel and stay connect to the network.
The BBC's Dan Johnson explores who has said what in the row and how the situation affects the war.
