IRNA – Refusing to provide fuel to Iranian passenger jets at the European and Turkish airports has nothing to do with the governments, the Iranian president's chief of staff, Mahmoud Vaezi, said on Wednesday putting the blame on private sector suppliers.

'It's a decision connected to the international companies and as they trade with dollar they do not supply Iranian planes with fuel,' Vaezi said.

US President Donald Trump withdrew from 2015 multilateral nuclear deal with Iran on May 8, arguing it did too little to constrain Tehran’s nuclear program.

He imposed two rounds of sanctions on Iran, the second of which came into force earlier this month.

Washington has said international companies that continue to do transactions with Iran will be cut off from the American market.

Regulations by the International Civil Aviation Organization oblige the airports of member countries to render equal services to airplanes of other member-states. Hence the refusal to fuel Iranian passenger jets at the European airports is against the international regulations.

The US is enforcing new sanctions on Tehran while the UN atomic agency has confirmed, in repeated reports, Iran’s compliance with its commitments under the deal.

Other signatories to the pact oppose Washington's move and insist that Iran nuclear deal has to be saved.
