Julian Assange, the founder of WikiLeaks, has been living in the Ecuadorean embassy in London since he was granted asylum by the South American country two years ago.

On Monday, Assange said he would be leaving the embassy but didn't elaborate, The New York Times reported. Some news outlets have reported that his health is in decline, accelerating his desire to vacate the embassy.

"I am leaving the embassy soon," Assange said, according to the Wall Street Journal. "But perhaps not for the reasons that the Murdoch press and Sky News are saying at the moment."

Quoting a WikiLeaks source, news reports said that Assange had heart arrhythmia, high blood pressure and a chronic lung condition.

If he leaves, Assange faces extradition to Sweden, where he faces accusations of sexual misconduct. He also could face the possibility of extradition to the U.S. because of his disclosure of confidential U.S. material through WikiLeaks.

The U.S. has not sought to extradite Assange over the leaks.

Ricardo Patino, Ecuador's foreign minister, reiterated his country's support of Assange at Monday's press conference and said he would continue negotiating an end to the legal battle.

"The situation must come to an end," Patino said. "Two years have been definitely too long. It is time to free Julian Assange, it is time for his human rights to be respected."

Since Assange has been at the London embassy, British police have kept a 24-hour watch on him at a cost of more than $10 million. Authorities in London have said they will not allow him to walk free.

A spokeswoman for WikiLeaks said that Assange would leave Britain if he was guaranteed safe passage but that he wouldn't turn himself in to authorities.

The WikiLeaks founder has not been charged in the sexual-misconduct case in Sweden that dates back to 2010, but he is sought for questioning. The case is focused on two women Assange met on a trip to Sweden. Assange denies the accusations.
