Tehran, Sep 21 (IANS): Iran has ruled out talks with the US on revisiting a 2015 nuclear accord as "waste of time", the media reported.

Iranian President Hassan Rouhani on Wednesday ruled out talks with U.S. President Donald Trump's administration on revisiting a 2015 nuclear accord and said Tehran had "various options" if Washington pulls out, Xinhua reported citing IRNA.

"An American government that chooses to trample on her legal and legitimate international commitments, a conversation with such a government would be a waste of time," Rouhani told reporters on the sidelines of the UN General Assembly.

Iranian Foreign Minister Mohammad Javad Zarif said there was no question of reopening negotiations, a day after Trump called the accord an "embarrassment".

Rouhani said that Iran had "various options" including "the removal of obstacles" if the US pulls out of the agreement.

"Iran has never sought, is not now seeking and will never seek nuclear weapons," he said.

The dispute centers on uranium enrichment, which Iran says is for civilian use but critics led by Israel say is intended to build nuclear weapons.
