Iran has released Washington Post reporter Jason Rezaian and three other Iranian-American prisoners as it anticipates the lifting of international sanctions.

Rezaian, 39, was convicted of espionage in Iran last year.
Iranian state TV named the other three as Saeed Abedini, Amir Hekmati and Nosratollah Khosravi.

Iran said they were being swapped for seven Iranians held in US prisons but there was no immediate US confirmation.
The Iranian state news agency listed the seven as Nader Modanlo, Bahram Mechanic, Khosrow Afghani, Arash Ghahreman, Tooraj Faridi, Nima Golestaneh and Ali Saboun.

In addition, Iranian state TV said 14 Iranians sought by the US would be removed from an Interpol wanted list.
News of the releases came after Iranian Foreign Minister Javad Zarif predicted that international sanctions against his country would be lifted.
