France, Britain and Germany say it is clear Iran is responsible for an attack on Saudi oil facilities on September 14 and have called on Tehran to agree to negotiations on its nuclear and missile programs as well as regional security issues.
"The time has come for Iran to accept a long-term negotiation framework for its nuclear program, as well as regional security issues, which include its missile programs," the three governments said in a joint statement on Monday.
French President Emmanuel Macron, British Prime Minister Boris Johnson and German Chancellor Angela Merkel met during the annual United Nations gathering of world leaders to coordinate their strategy on Iran as the European parties seek to save a 2015 nuclear deal and defuse tensions between Washington and Tehran.
"It is clear to us that Iran bears responsibility for this attack. There is no other plausible explanation," a statement by the three leaders said.
With Johnson laying the blame on Iran earlier in the day, it was the first time Paris and Berlin had done so.
The three countries said they remained committed to the 2015 Iran nuclear deal but demanded that Tehran return to full compliance after reneging on some of its commitments.
"We are committed to continuing our diplomatic efforts to create conditions and facilitate dialogue with all relevant partners interested in de-escalation of tensions in the Middle East," they said.
Meanwhile, the US will intensify pressure on Iran over the attacks, US special envoy for Iran Brian Hook said on Monday but added Washington was seeking a global coalition countering Tehran and that it was going to act "prudently".
"It is that Iran has crossed the line by this attack on another country's sovereignty," Hook said at an Asia Society event in New York.
Hook said the US was seeking to address the issue through diplomacy and a multilateral effort and that there was a role for the United Nations Security Council to play.
