The European Union is poised to ban imports of Iranian gas into Europe as part of its efforts to ratchet up pressure on the Islamic Republic over its nuclear programme, diplomats said on Thursday.

Diplomats from EU member states have started preparing a package of sanctions against Iran [1] with a goal of formally adopting them at a meeting of foreign ministers on Oct. 15 in Luxembourg.

Late on Wednesday, they reached a preliminary deal to ban gas imports, the first measure to win approval in the package, which also consists of various finance [2] and energy-related proposals, three EU diplomats said.

"There is agreement on gas," one of the diplomats said, speaking on condition of anonymity. "The big states back it, Germany, Britain, France [3]," another one said.
