Russia & China will block any efforts to take Iran to the UN security council

Russia and China have openly opposed Western efforts to take Iran to the UN Security Council over Tehran's controversial nuclear activities.
The US and EU have been pressing for Iran to be referred to the Security Council, which can impose sanctions.
But Moscow and Beijing may block the plan, with Russia saying the current situation was "not irreversible".
Iran has threatened to bar snap inspections of its nuclear sites if it is referred to the Security Council.
Iran's chief nuclear negotiator Ali Larijani also said Tehran would also consider pulling out of the nuclear Non-Proliferation Treaty (NPT) and resume uranium enrichment if the "language of force" continues.
