Ecuador’s Foreign Minister on Tuesday said he doesn’t know where Edward Snowden is after the National Security Agency whistleblower failed to board a flight from Russia.

Ricardo Patino spoke a day after an Aeroflot plane with a seat registered for Mr. Snowden flew to Cuba without him. Ecuador is considering an asylum request from Snowden, who is wanted by the United States on espionage charges.

Mr. Patino told reporters in Hanoi, Vietnam, where he is travelling, “I don’t know exactly where he is right now.”

WikiLeaks founder Julian Assange has said Mr. Snowden was safe but he couldn’t elaborate. The secrets-spilling organization has embraced Mr. Snowden and his efforts to gain asylum.
