Britain and Ecuador failed to reach agreement on the fate of WikiLeaks founder Julian Assange Thursday at a meeting of their foreign ministers here, officials said.

"We see no immediate solution," Ecuadoran Foreign Minister Ricardo Patino told reporters after meeting with British Foreign Secretary William Hague on the sidelines of the UN General Assembly.

Hague told Patino "that the UK was under an obligation to extradite Mr Assange to Sweden," a spokesman for the British foreign secretary said in a statement.
