World powers to discuss Iran sanctions on Friday

World powers will meet in London on Friday to discuss further sanctions against Iran to keep pressure on it over its nuclear programme, Britain's Foreign Office confirmed on Thursday.

"Political directors from the UK, France, Germany, U.S., Russia and China will meet ... to discuss next steps on Iran's nuclear programme," a Foreign Office spokesman said.

"The UK supports a further United Nations Security Council resolution if Iran does not comply with its international obligations. At Friday's meeting we will want to hear from colleagues how they see the process going forward."
