Germany's Maas warns Iran to return to nuclear commitments

The deal - which aims to prevent Iran from developing a nuclear bomb in return for far-reaching sanctions relief - has been at risk ever since Washington pulled out last year and reimposed tough economic restrictions, prompting Tehran to scale back its compliance.
"We want to maintain the JCPOA, but then Iran must finally return to its commitments," Maas said ahead of a meeting in Brussels with his EU counterparts.
"Otherwise we will reserve the right to use all mechanisms specified in the deal," Maas added. The nuclear accord foresees a dispute resolution mechanism to deal with Iranian breaches.
The multi-stage process could ultimately allow countries to cease implementing the JCPOA, which would mean the reimposition of sanctions and UN Security Council notification.
Maas said he would meet with his French and British counterparts in Paris later on Monday to discuss the way ahead, expressing "great concern" about Iran's new nuclear enrichment activities.
"I am very worried about Iran's behaviour," added Dutch Foreign Minister Stef Blok, while his Luxembourg counterpart Jean Asselborn said now was not the time to mull new sanctions.
"Sanctions ... will not resolve the problem," Asselborn said.
