Iran announced on Wednesday it had launched a rocket carrying several small animals into space.
An Iranian state-run news agency said the rocket was launched to commemorate the anniversary of the Iranian Revolution on Feb. 11. The launch of the rocket also coincided with Iran's Space Day, according to the Los Angeles Times.
Last year when Iran announced that it was planning a series of satellite launches the U.S. government expressed concerns over the matter.
"Although this appears to be [a] satellite, there are dual-use capabilities that could be applied to missiles, and that's a concern to us and everybody in region," said a U.S. Defense Department spokesman at the time.
According to CNN the Pentagon dismissed claims made by Iran in 2008 saying that they has launched a vehicle into orbit capable of carrying a satellite. The Pentagon said the rocket was too unstable to leave Earth's atmosphere.
