Iran announced on Saturday that the second live monkey they recently launched into space was brought back safely, Reuters reported.
According to state news agency IRNA, the Middle Eastern country's eat demonstrates the country's missile capabilities.
"President Hassan Rouhani ... congratulated Iranian scientists and experts on successfully sending a second living creature into space," the news agency said.
Rouhani took to Twitter to announce the latest event, "a demonstration of rocket power that is likely to cause concern in the West and among some Gulf states, which are worried about Iran's nuclear ambitions," Reuters reported.
He said the monkey, whose name was named Fargam, returned to earth "safe and sound."
"In total, this is the second monkey sent into space and returned in perfect health to Iran," Rouhani said in another Twitter message.
Iran said it launched its first monkey to space in January.
Reuters reported this feat concerns the West. They reportedly are worried that the long-range ballistic technology used to propel Iranian satellites into orbit could be put to use dispatching nuclear warheads to a target.
Last month, the world's six powers made a breakthrough deal for Tehran, the capital of Iran, to phase out its nuclear program in return for limited sanctions easing.
Russia on Friday warned that expanding a U.S. sanctions blacklist could seriously complicate the deal's implementation, Reuters reported.
"We are aware of reports that Iran has launched an object into space," Bernadette Meehan, a spokeswoman for the U.S. National Security Council, told Reuters. "Our concerns with Iran's development of space launch vehicle technologies are well-known, and we continue to monitor these developments closely."
Riki Ellison, a U.S. missile defense expert, told Reuters, the launch showed Iran had not halted work on its long range missile development program.
"If it's true, they continue to expand and grow their long range missile capabilities regardless of their overture to the West with self reduction of their nuclear capabilities," Ellison said.
Iran's Gulf Arab neighbors also view Iran missile capabilities as a threat.
"Saudi Arabia and the United Arab Emirates have spent heavily in the past few years on advanced U.S.-made missile defense systems," Reuters reported.
Iran's efforts to develop and test ballistic missiles and build a space launch capability have contributed to Israeli calls for pre-emptive strikes on Iranian nuclear sites and billions of dollars of U.S. ballistic missile defense spending.
