Israel's leader says the international community must insist on a "better deal" with Iran over its suspect nuclear program.

Benjamin Netanyahu says Wednesday that while world powers are making concessions to the Islamic Republic it continues to wreak havoc in the Middle East and threaten Israel with annihilation. He says a weak deal will endanger not only Israel but world peace.

He says a better deal would "significantly roll back Iran's nuclear infrastructure" and link a lifting of restrictions to "a change in Iran's behavior."

Netanyahu has been a fierce critic of a looming deal that would allow Iran to continue enriching uranium.

Iran nuclear negotiators continued talks Wednesday in Switzerland after abandoning a March 31 deadline to reach the outline of a deal.
