Iran has rejected a joint statement by the leaders of France, Germany and the UK who blamed it for attacks earlier this month on Saudi oil installations.
Iran's foreign minister accused them of “parroting absurd US claims”.
The European leaders said there was no other plausible explanation for the attacks, which shut down half of Saudi Arabia's oil production.
But they said they remained committed to the 2015 international deal on Iran's nuclear programme.
Yemen's Iran-aligned Houthi rebels have claimed they carried out the 14 September attacks while Iran itself has denied any involvement.
Eighteen drones and seven cruise missiles hit an oil field and processing facility.
Saudi Arabia has blamed Iran for the attacks, as has the US which is sending more troops to the kingdom.
What did the leaders say?
British Prime Minister Boris Johnson, French President Emmanuel Macron and German Chancellor Angela Merkel issued their statement on the sidelines of the UN General Assembly in New York.
“It is clear to us that Iran bears responsibility for this attack. There is no other plausible explanation. We support ongoing investigations to establish further details,” they said.
“The time has come for Iran to accept negotiation on a long-term framework for its nuclear programme as well as on issues related to regional security, including its missiles programme and other means of delivery,” the statement added.
