JERUSALEM (Reuters) -Israeli Prime Minister Benjamin Netanyahu on Sunday repeated calls for Iran's entire nuclear infrastructure to be dismantled, as Washington and Tehran engage in talks for a nuclear accord.

After a third round of talks in Oman over the weekend to put controls on Iran’s nuclear program in exchange for lifting sanctions, Iranian officials and President Donald Trump are sounding optimistic.

Washington opposes Tehran’s insistence on retaining the ability to enrich uranium, but U.S. calls latest round “productive.”
