At odds with ally Washington over an emerging nuclear agreement with Iran, Israeli Prime Minister Benjamin Netanyahu will on Wednesday take his campaign against the deal to Moscow.

The P5+1 will meet with Iran on Wednesday in Geneva for talks on the nuclear program.

Netanyahu vehemently opposes the proposed deal, claiming it will give Iran vital sanctions relief while failing to halt Tehran's alleged march towards a "breakout" nuclear weapons capability.

An Israeli official told AFP ahead of the trip, "We'd like (the Russians) to have a better understanding of our concerns and the need to prevent Iran from having a breakout capacity."

"A breakout capacity means that they have the capability to develop a nuclear weapon at a time and a place of their choosing in the future."
