The British, French and German governments are expected to push for a further tightening of sanctions by the end of the month.

But at a recent meeting, Israeli nuclear chief Shaul Horev told diplomats that any deal for a nuclear-free zone under the U.N. would amount to “external coercion,” as opposed to “local initiative.”
