According to Iranian state TV, the Iranian nuclear chief said that the EU should make up for the US withdrawal from the nuclear deal or Tehran would enrich uranium "stronger than before."
"The European signatories should make up for the US withdrawal from the JCPOA and guarantee our rights. … If they cannot do that, we are ready to take our nuclear programme to a level stronger than before the JCPOA," Ali Akbar Salehi said in an interview.
On May 8, President Donald Trump violated the terms of the JCPOA by withdrawing from the accord.
The move has been strongly criticized by other P5+1 members, Moscow, London, Beijing, Paris, Berlin and Brussels, who have confirmed their commitment to the deal.
Tehran has expressed its opposition to Trump's move.
On July 14, 2015, the European Union and the P5+1 group of countries — China, Germany, France, Russia, the United Kingdom and the US — signed the JCPOA with Iran. The JCPOA has ensured that Iran's nuclear program remains peaceful in exchange for sanctions relief.
