Israeli Prime Minister Benjamin Netanyahu on Sunday urged world powers to stand firm in negotiations over Iran's nuclear program, a day after a US official said the Islamic Republic may be able to keep some of its enrichment capabilities, Ynet reported. "We need to dismantle Iran's ability to manufacture and launch nuclear weapons," Netayahu said during his weekly cabinet meeting. "This has yet to be achieved, and without the persistence of the world powers it will not be achieved... I hope that the powers will be firm in the demand to prevent Iran from becoming a nuclear-threshold country."
