US President on Sunday said Iran “better be careful,” hours after Tehran announced it would shortly boost its uranium enrichment.

Iran Press/America: Speaking to reporters as he departed Morristown, New Jersey for Washington, D.C., Trump also took aim at the British Ambassador to the US, Kim Darroch, saying he did not serve the United Kingdom well, after a news report alleged he criticized Trump administration in a series of confidential memos.

Meanwhile, US Secretary of State Mike Pompeo said on twitter that Iran will face further sanctions after Iran said it would keep reducing its commitments every 60 days unless signatories of the pact protected it from US sanctions imposed by President Trump. 

On Sunday, Iranian Deputy Foreign Minister Abbas Araghchi said that Iran is going to take the second step towards the reduction of its commitments within JCPOA, with uranium enrichment exceeding the %3.67 percent limit.

US act against Iran, a bitter joke: Araghchi

Speaking at a press conference in Tehran on Sunday, Araghchi elaborated on Iran's new decisions regarding its commitments to the JCPOA. The Iranian Deputy Foreign Minister Abbas Araghchi went on to say it is ironic the US which withdrew from the Joint Comprehensive Plan of Action (JCPOA) has asked Board of Governors of the International Atomic Energy Agency (IAEA) to act on what Washington calls a violation of the agreement by Iran, although US violated JCPOA itself. Araghchi also said the US demand from IAEA vis-a-vis Iran is like a bitter joke.
