Iran announced it has begun using advanced centrifuges to enrich uranium.
The explosion marked the third failure involving a rocket at the Imam Khomeini Space Center, raising suspicion of sabotage.
Donald Trump had said Monday at the G-7 that there's a "really good chance" that he and Hassan Rouhani could meet to discuss their nuclear impasse.
The announcement comes as Iran’s nuclear deal with world powers is unraveling.
WHAT'S HAPPENING
The report comes just days after an oil tanker based in the United Arab Emirates disappeared off trackers in Iranian territorial waters.
Tehran said Sunday that it will raise its uranium enrichment level beyond the 3.67% limit set in the 2015 nuclear deal.
It's a major departure from the 2015 nuclear deal, a year after the U.S. unilaterally withdrew from the accord.
The measures target Iranian Supreme Leader Ayatollah Ali Khamenei and his office.
President Donald Trump said he was imposing more sanctions but still wanted to strike a deal to ease tensions with Iran.
At the root of the recent spike in tensions appears to be Trump’s decision a year ago to pull out of the nuclear deal.
