Israeli President Isaac Herzog has said the “Houthis have crossed a red line in the Red Sea” after commercial vessels were fired on by gunmen in a speedboat and targeted with missiles.

It is the latest incident to threaten the shipping lane after Yemeni Houthi forces warned ships not to travel to Israel.

“The US-led international activities against the Houthi terror pirates must be bolstered and strengthened, in the form of a truly international coalition,” Herzog said.
