United States Secretary of State Antony Blinken said in an interview on CBS News that "since we pulled out of the nuclear deal and then Iran began to ignore the constraints that the deal had imposed on it, it has been galloping forward, and it's enriching more material."

Blinken claimed that Iran "is enriching at higher degrees than were allowed under the agreement."

Last month, secretary Blinken claimed that Iran did not indicate its willingness to return to the JCPOA.

Hossein Amirabdollahian, the special aide to the President of the Islamic Parliament of Iran in International Affairs, said that his country is rapidly developing its peaceful nuclear program, warning the European countries of decisive Iranian decisions in case they don't respect the rights of the Iranian people.

On Twitter, Amirabdollahian noted that the European Troika called on Iran to cooperate with the International Atomic Energy Agency instead of fulfilling its obligations.

على الرغم من تنفيذ إيران الكامل لالتزاماتها، دعت الترويكا الأوروبية #إيران إلى التعاون مع IAEA بدلاً من الوفاء بالتزاماتها. تطور إيران بقوة برنامجها النووي السلمي، وتؤكد على رفع الحظر واختبار صدق النوايا. وإذا لم يحترموا حقوق الشعب الإيراني، فليترقبوا قرارات طهران الحاسمة.

Abbas Araghchi, Iran's chief negotiator in the Vienna talks, ruled out Sunday reaching an agreement in the sixth round of the negotiations.

After the nuclear talks started in Vienna between Tehran and Washington, the Chinese Foreign Minister announced that the talks are in the "final stage," saying that "the acts of bullying are solved unilaterally... by the United States."

The main differences in the talks revolve around the sanctions that the United States should lift and the steps that Iran should take to resume fulfilling its obligations under the agreement, which limits its nuclear program, according to the Wall Street Journal published earlier this month.
