WikiLeaks founder Julian Assange has been barred from using the internet at the Ecuadoran Embassy in London for supposedly interfering in other countries' affairs.
The Ecuadorian government says he violated an agreement with the embassy, where he has been holed up for nearly six years, to not comment on international issues.
It added his social media activity put Ecuador's good relations with the UK, EU and other nations at risk.
Assange recently expressed strong support for separatist leaders in Spain's Catalonia region.
He also was engaged in a heated clash of words with a British minister on Twitter, questioning London's claim that Russia was behind the poisoning of a former Russian spy in Salisbury.
