Israel should avoid taking any action that would undermine the interim nuclear agreement reached between Iran and world powers, Britain's Foreign Secretary William Hague said on Monday. "We would discourage anybody in the world, including Israel, from taking any steps that would undermine this agreement and we will make that very clear to all concerned," Hague was quoted by Jerusalem Post as telling the parliament. Hague, who gave an update on the nuclear talks in Geneva, added he had not seen any signs that any country opposed the agreement would try to disrupt it "in any practical way" but said Britain would be "on its guard". He was speaking after Israeli Prime Minister Benjamin Netanyahu on Sunday denounced the nuclear deal as an "historic mistake". Netanyahu is sending his national security adviser to Washington for talks about the agreement. Hague told parliament he hoped a comprehensive nuclear agreement with Tehran could be reached within a year, but warned that world powers could swiftly reverse any sanctions relief they had granted Iran if Tehran reneged on the deal. Meanwhile French and EU officials said on Monday that the EU could relax some sanctions on Iran as soon as next month.
