The European Union Council has asked Iran to comply with the 2015 arms control agreement that prevents it from developing nuclear weapons.

EU Council President Charles Michel, said he had spoken to Iran’s President Hassan Rouhani on the developing issues in the region.

Iran had during the week said that it was stepping back from its commitments under the deal, known as the JCPOA following US attack that killed Qassem Soleimani.

“Just spoke with @HassanRouhani about recent developments. JCPOA remains crucial for global security. I called Iran not to pose irreversible acts,” Michel, who coordinates EU government positions in Brussels, said in a tweet.
