Turkish Prime Minister Recep Tayyip Erdogan said Iran would be on its own if it failed to fulfil conditions of a fuel swap deal and deliver uranium to Turkey within one month.

His comments, at a news conference in Madrid, came after Tehran agreed with Brazil and Turkey on Monday to send uranium abroad, reviving a fuel swap plan drafted by the United Nations with the aim of keeping Iran’s nuclear activities in check.

“If Iran does not fulfil its duty within one month, naturally Iran will be on its own,” said Erdogan. “If Iran does not live up to its expectations, Brazil and Turkey will take a step forward and get out of the picture.”

Earlier, Erdogan questioned the credibility of permanent U.N Security Council members who maintain their nuclear capability while calling on other countries to abandon their weapons

“Where is your credibility if you have nuclear weapons but are telling other countries not to have them,” he said while visiting the European University in Madrid, Reuters reported.
