"The concessions offered to Iran in Lausanne would ensure a bad deal that would endanger Israel, the Middle East and the peace of the world. Now is the time for the international community to insist on a better deal," Netayanu said in a statement published on his official Facebook page.
He stated that an Iranian general on Tuesday had declared that "Israel's destruction is non-negotiable."
"A better deal would significantly roll back Iran's nuclear infrastructure. A better deal would link the eventual lifting of the restrictions on Iran's nuclear program to a change in Iran's behavior," Netanyahu said.
The Israeli prime minister has long criticized efforts by international mediators to reach a negotiated settlement on the peaceful use of nuclear energy in Iran.
Iran and the P5+1 group comprising Russia, the United States, the United Kingdom, France, China and Germany, are currently hammering out a framework for the comprehensive agreement on Tehran's nuclear energy program during talks in Lausanne.
