This is the latest escalation by the Houthis, which have proven they are not going to stop attacking ships, despite the US and other countries acting to strike their capabilities.
An advisor to the Yemeni information minister blamed the Iran-backed Houthis for the general's death.
The overall context then is that the Houthis and Hezbollah are both vowing to step up attacks, despite the fact they have faced opposition from the US and Israel respectively.
Over 200 packages containing medium-range ballistic missile components, explosives, unmanned underwater/surface vehicle (UUV/USV) components, and more, had been seized.
Yemen has been mired in conflict since Houthis ousted the government from the capital Sanaa in late 2014. The Saudi Arabia-led military coalition intervened in 2015.
The sea may develop into an arena requiring greater Israeli effort, but could also create additional opportunities for international cooperation, and not only in the Red Sea.
Houthi operations in the Red Sea were "legitimate (ones) to help support the people of Gaza and lift the siege being imposed on them," according to a spokesperson for the terror organization.
