FNA - Chairman of the Iranian parliament's Nuclear Committee Mojtaba Zonnour underlined that the European states should take practical steps to protect the 2015 nuclear deal or face Tehran's tough and unprecedented reaction.

"Now, we are facing a shaky and unstable nuclear deal," Zonnour said on Sunday.

"If the Europeans fail to meet Iran's interests after the US withdrawal, the Islamic Republic of Iran's reaction will be different from the past," he added.

In relevant remarks earlier this month, Iranian Parliament Speaker Ali Larijani warned the European states that the time demanded by them to persuade Tehran to remain committed to the 2015 nuclear deal after the US withdrawal is ending.

"The US and Israel have hatched plots against Iran and they annulled an agreement that they themselves had demanded. The European leaders demanded Iran not to give a rapid response to this move and they urged Iran to wait for a while. Now this time is passing," Larijani said, addressing a gathering in the Southern province of Fars.

He also cautioned about Washington's plan to zero Iran's oil export, and expressed pleasure that oil plays a 30-percent role in the country's budget.

Larijani reminded Supreme Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei's emphasis on the necessity for the reduction of the country's dependence on oil revenues.
