If this happens, it will be another big blow to Iran following international oil sanctions which have this week led to a sharp drop in the local currency, the rial, against the US dollar.
Reuters reported on Thursday that EU diplomats have started to put together plans to ban the import of Iranian gas ahead of a meeting of foreign ministers on 15 October.
The news wire cited three unidentified EU diplomats as saying that a preliminary deal on banning gas imports was agreed late on Wednesday.
“The big states back it: Germany, Britain, France,” one of the sources told Reuters.
Iran is currently struggling under the weight of international sanctions against its crude oil and other industries. The sanctions are aimed at crippling the country’s perceived nuclear weapons programme. Iran has always contended that the programme is for civilian use only.
