Israeli PM Naftali Bennett directed a message at Iran following the attack on the "Mercer Street" ship.
"In recent days, the world has received another reminder of Iranian aggression, this time at sea. The Iranians, who attacked the ship Mercer Street with unmanned aircraft, aimed to hit an Israeli target. Instead, their pirate act resulted in the deaths of a British citizen and a Romanian citizen.
"I send from here our condolences to Britain and Romania , and of course to the families of the victims.
"I have just heard that Iran, in a cowardly way, is trying to evade its responsibility for the incident, they deny it. So I state here absolutely: Iran is the one that carried out the attack against the ship.
"Iran's bullying is dangerous not only for Israel, but also harms global interests, freedom of shipping and international trade.
"The intelligence evidence for this exists and we expect the international system to make it clear to the Iranian regime that they have made a grave mistake.
"In any case, we know how to convey the message to Iran in our own way."
