Iranian Supreme Leader Ayatollah Ali Khamenei endorsed the multinational pact on his country’s nuclear program on Wednesday, days after the agreement took effect.
Khamenei — who has the final say on all policy matters in Iran — had so far declined to either explicitly endorse or oppose the agreement, but was believed to have tacitly supported it before Iranian lawmakers approved it last week.
{mosads}In a letter to Iranian President Hassan Rouhani, Khamenei said that he supported the deal but nonetheless warned about the actions of the United States, according to multiple reports.
He also warned about “ambiguities” in the pact that could “bring huge damages” to Iran.
On his English-speaking Twitter account, Khamenei said that the Obama administration has been involved in “internal conspiracies” to bring down the Iranian government.
The seven-nation nuclear deal went into effect over the weekend, three months after it was signed by international negotiators. In exchange for Iran’s actions to limit its nuclear program, the U.S. and other world powers will lift crippling sanctions on its oil and financial sectors.
International sanctions will not be lifted on Iran until after it has taken a number of steps to comply with the deal.
