Ecuador's Government says it has cut off WikiLeaks founder Julian Assange's internet access at the nation's London embassy after his recent activity on social media decrying the arrest of a Catalonian separatist leader.

Key points: Julian Assange questioned the blaming of Moscow in spy poisoning case

Julian Assange questioned the blaming of Moscow in spy poisoning case Ecuador granted Mr Assange asylum in 2012

In a statement, officials said Mr Assange's recent posts "put at risk" the good relations Ecuador maintains with nations throughout Europe and had decided as of Tuesday to suspend his internet access, "in order to prevent any potential harm".

Mr Assange had also questioned accusations Moscow was responsible for the poisoning of former spy Sergei Skripal and his daughter Yulia with a nerve agent on British soil.

He has since gone silent on social media.

Ecuador granted Mr Assange asylum in its embassy in 2012, where he has remained ever since.

The South American nation has repeatedly tried to find a solution that would allow Mr Assange to leave without the threat of arrest, but with no success.

He remains subject to arrest in Britain for skipping bail and also fears a possible US extradition request based on his leaking of classified US State Department documents.

Relations between Mr Assange and his host nation have often grown prickly.

Ecuador suspended his internet access in 2016 after a WikiLeaks dump targeting Hillary Clinton's presidential campaign.

Former president Rafael Correa hailed Mr Assange's work but the nation's current head of state has called him a hacker and warned him not to meddle in politics.

'Miserable little worm' should turn himself in

Mr Assange faces arrest by British authorities for breaching his bail terms should he step outside the embassy.

"It's of great regret that Julian Assange remains in the Ecuador embassy," junior minister Alan Duncan said during a question-and-answer session on foreign affairs in Parliament's House of Commons.

"It's about time that this miserable little worm walked out of the embassy and gave himself up to British justice."

Mr Assange responded to Mr Duncan's comment with a tweet.

"As a political prisoner detained without charge for 8 years, in violation of 2 UN rulings, I suppose I must be 'miserable'; yet nothing wrong with being a 'little' person although I'm rather tall; and better a 'worm', a healthy creature that invigorates the soil, than a snake," he said.

Last month, a British judge refused to halt legal proceedings against Mr Assange for jumping bail and said he was, "a man who wants to impose his terms on the course of justice".
