Former Israeli foreign minister and Leader of Yisrael Beytenu party Avigdor Lieberman has strongly attacked his former political partner Prime Minister Benjamin Netanyahu on Sunday, Ynet reported Sunday.

The remarks came in the wake of two recent terror attacks that Israel has lost its deterrence.

"I think that there has been a loss of deterrence. My position was very clear before and after Operation Protective Edge, and unfortunately the government did not accept my opinion. We see today's reality," he said.

"There is no deterrence," the former foreign minister stressed. "On the contrary, they are succeding at deterring us. We are buying peace from them at the cost of them restoring their terrorist infrastructure."

Lieberman repeated his assessment that Netanyahu's fourth government will fall apart by the end of 2015 and that he believes the next elections will be held in the spring of 2016.
