Israeli Prime Minister Naftali Bennett said Sunday Israel was privy to "evidence" proving Iran was behind the deadly tanker attack off Oman, warning his country could "send a message" in retaliation.

"The intelligence evidence for this exists and we expect the international community will make it clear to the Iranian regime that they have made a serious mistake," he said at the weekly cabinet meeting in remarks conveyed by his office.

"In any case, we know how to send a message to Iran in our own way."
