The US president warned Iran against restarting its nuclear program.
"I would advise Iran very strongly not to start nuclear program. If they do, there will be very severe consequences," Trump told reporters.
Following Trump's statement, a senior US administration official said that the US was ready to involve all countries in negotiations over its withdrawal from the Joint Comprehensive Plan of Action (JCPOA).
"We would be open to engaging all countries who have a concurrent interest in constraining the totality of… Iran's behavior. This does not have to be simply the JCPOA," the official said.
At the same time, according to the official, the US demands Iran to report on the country's military branch of its nuclear program and insists that the Middle Eastern country shouldn't enrich uranium, despite the US withdrawal from the deal.
In response to the US move, Iranian President Hassan Rouhani said the same day that Tehran was not going to withdraw from the JCPOA and that the agreement remained between Iran and the five remaining participants of the deal.
The JCPOA (The Joint Comprehensive Plan of Action) was signed on July 14, 2015 by the European Union and the P5+1 group of countries — China, Germany, France, Russia, the United Kingdom and the United States. The accord stipulated a gradual lifting of anti-Iranian sanctions in exchange for Tehran curbing its nuclear program and allowing inspections to ensure that the nature of the program is peaceful.
