US - Iran Nuclear weapons dealWatch
Mr Netanyahu says the deal would be inadequate to prevent Tehran from acquiring a nuclear bomb. He is due to give a speech in Congress on Tuesday which was not agreed in advance with the Obama administration, angering the White House. The US and other powers, the so-called P5+1, are negotiating with Iran on its nuclear programme.
They want a framework agreement by the end of the month which addresses concerns that Iran is seeking nuclear weapons technology, something Tehran denies.
