Top Revolutionary Guard: 'EU can't save Iran nuclear deal after US move'

European countries are powerless to salvage the nuclear deal with Iran after the United States' decision to pull out, the deputy head of the elite Iranian Revolutionary Guards (IRGC) was quoted on Thursday as saying.

"Europe cannot act independently over the nuclear deal," Brigadier General Hossein Salami said, according to the semi-official Fars news agency, after Britain, France and Germany said they remained committed to the deal.

"Iran's enemies are not seeking military confrontation. They want to pressure our country by economic isolation ... Resistance is the only way to confront these enemies, not diplomacy," Salami was quoted as saying.

Iranian President Hassan Rouhani said on Tuesday that Tehran would remain in the 2015 deal despite President Donald Trump's decision to withdraw, but added that he thought Europe had only a "limited opportunity" to preserve the pact.
