A British judge refused on Tuesday to halt legal proceedings against WikiLeaks founder Julian Assange for jumping bail and fleeing to the Ecuadorean embassy in London in June 2012.

The ruling leaves Assange, 46, in a legal and diplomatic impasse, with no way out of the embassy where he has lived for almost six years, unless he decides to face the prospect of arrest by British police.

Assange said on Twitter he had three months to appeal the ruling, without specifying whether he would. He said the judge's ruling contained "significant factual errors" which he did not spell out.
