Yemen's Houthi armed forces announced a "complete and total ban" on Israeli maritime navigation in the Red Sea on Monday, declaring that all Israeli-affiliated vessel movements would be considered military targets from the moment of the announcement.
The group simultaneously claimed missile strikes on sensitive targets in the Israeli port city of Jaffa, Houthi spokesman Brigadier General Yahya Saree said.
The Yemeni Armed Forces said they fired a missile salvo targeting "sensitive targets of the Israeli enemy" in occupied Jaffa.
The statement said the attack "achieved its objectives with precision."
The strike was framed in the context of confronting what the group described as "American-Zionist aggression against Iran, Palestine, Lebanon, Iraq, and Yemen," and in solidarity with what it called the "axis of resistance."
"We announce a complete and total ban on maritime navigation for the Israeli enemy in the Red Sea, and we consider all the enemy's movements to be military targets for our armed forces from the moment of the announcement of this statement," the Yemeni Armed Forces statement said.
"We will confront escalation with escalation," the group said, adding that its "military operations will be escalating in line with the events, the battle, and the participation with the axis of resistance."
The Houthis also said they would "not stand idly by in the face of the unjust siege on our people and the peoples of the axis of jihad and resistance in Palestine, Gaza, Iran, Lebanon, and Iraq."
Israeli Army Radio reported that the Israeli military assessed the campaign against Iran could last several days, with a "large-scale mobilization of reserves" underway.
Reporter Doron Kadosh said the military would reinforce forces at borders, particularly the occupied West Bank-Jordan border, and that the Israeli Home Front Command had also begun a large-scale reserve mobilization.
