Quito: Ecuador has denied it gave a travel document to fugitive US intelligence leaker Edward Snowden that allowed him to travel from Hong Kong to Russia.

"This is not true. There is no passport, no document that was delivered by any Ecuadoran consulate," senior foreign ministry official Galo Galarza told reporters.

"He doesn't have a document supplied by Ecuador like a passport or a refugee card as has been mentioned," Mr Galarza added.

WikiLeaks founder Julian Assange, who has been assisting Mr Snowden, said on Monday that Quito had issued the former National Security Agency contractor a "refugee document of passage" after the United States revoked his passport.
