The US is piling huge amounts of firepower into the Red Sea to combat Houthi attacks on vital shipping routes

• The Houthi militia in Yemen is launching waves of attacks on ships in the Red Sea. 
• The US is deploying a major firepower to shoot them down. 
• The Houthis — allies of Iran — began their attacks after Israel's counterattack on Gaza. 

The US response to waves of attacks by Islamist militants on commercial ships in the Red Sea has so far been restrained.

But behind the scenes the Pentagon is deploying acres of firepower to the region, sending more than than it has in decades, The Times of London reported, citing Pentagon sources.
