Netanyahu warned Kerry and his European counterparts that Iran would be getting "the deal of the century" if they carried out proposals to grant Tehran limited, temporary relief from sanctions in exchange for a partial suspension of, and pledge not to expand, its enrichment of uranium for nuclear fuel.
"Israel utterly rejects it and what I am saying is shared by many in the region, whether or not they express that publicly," Netanyahu told reporters.
"Israel is not obliged by this agreement and Israel will do everything it needs to do to defend itself and the security of its people," he said before meeting Kerry in Jerusalem.
The White House responded by saying it was "premature" To criticize what was being deliberated in Geneva.
"There is no deal, but there is an opportunity here for a possible diplomatic solution, and that is exactly what we are pursuing," said Josh Earnest, deputy White House spokesman. "So any critique of the deal is premature."
