DOHA, Sept 18 (Reuters) - U.S. officials received the five freed Americans released by Tehran after they disembarked from a Qatari plane at Doha international airport on Monday, a Reuters witness said.

Earlier, the five U.S. detainees had flown out of Iran in a swap for five Iranians held in the United States, in a rare deal between the arch enemies that also unfroze $6 billion of Tehran's funds. (Reporting by Andrew Mills Editing by Gareth Jones)
