Iran says it has successfully sent a monkey into space.
The primate travelled in a Pishgam rocket, which reached an altitude of some 120km (75 miles) for a sub-orbital flight before "returning its shipment intact", the defence ministry said.
Iranian state TV showed images of the monkey, which was strapped into a harness, being taken to the rocket.
Western nations have expressed concern that Iran's space programme is being used to develop long-range missiles.
Such missiles could potentially be used to carry nuclear warheads.
Iran denies it is seeking to develop nuclear weapons and insists its nuclear programme is solely for peaceful purposes.
In 2010, Iran successfully sent a rat, turtle and worms into space. But an attempt to send a monkey up in a rocket failed in 2011.
President Mahmoud Ahmadinejad announced in 2010 that the country planned to send a man into space by 2019.
A domestically-made satellite was sent into orbit for the first time in 2009.
