After the United States and the UK launched a series of airstrikes in Yemen against the Houthis, who have been attacking ships in the Red Sea, the Shia Islamist political and military organization issued a defiant tweet claiming the aggression "will not go unanswered." The post was made by their spokesman Mohammed Al-Bukhaiti:

The US-British coalition’s bombing of a number of Yemeni provinces will not change our position, and we affirm that our military operations against Israel will continue until the crimes of genocide in Gaza are stopped and the siege on its residents is lifted, no matter the sacrifices it costs us.

Our war is moral, and if we had not intervened to support the oppressed in Gaza, humanity would not have existed among humans.

The American-British aggression against Yemen will not go unanswered, and we will meet escalation with escalation.

Although written in English, it's unclear what the sentence "Our war is moral, and if we had not intervened to support the oppressed in Gaza, humanity would not have existed among humans" means. 

He also posted a similar tweet in Arabic:

عملياتنا العسكرية ضد الكيان الصهيوني ستستمر حتى وقف العدوان على غزة مهما كلفنا ذلك من تضحيات، وسنقابل التصعيد بالتصعيد، وما النصر إلا من عند الله. pic.twitter.com/gqbRqf3q48

According to Google Translate, the post says:

Our military operations against the Zionist entity will continue until the aggression against Gaza stops, no matter what sacrifices it costs us. We will meet escalation with escalation, and victory comes only from God.

The bellicose language comes after Iran's Islamic Revolutionary Guards Corps (IRGC) Quds Force and its proxy militia groups were hammered by military strikes Friday. On Saturday, it was the Houthis' turn, as reported by RedState's Jeff Charles:

The United States and Britain carried out large-scale military strikes on Saturday against multiple sites in Yemen controlled by Houthi militants, according to a statement from the two countries and six supporting allies, as the Biden administration continued its reprisal campaign in the Middle East targeting Iran-backed militias.

The attacks against 36 Houthi targets at 13 sites in northern Yemen came barely 24 hours after the United States carried out a series of military strikes against Iranian forces and the militias they support at seven sites in Syria and Iraq. 

Although Houthi attacks have become commonplace in the Red Sea, it was only after three U.S. Army Reservists were killed by a drone strike in Jordan that American forces brought this level of force. (The drone attack is believed to have been carried out by the Iranian-sponsored terrorist group Kataib Hezbollah.)

As we reported, National Security Advisor Jake Sullivan said on ABC's "This Week" Sunday that there could be more U.S. strikes in the future:

Well, the first thing that I would say, and you noted it at the top of your program, is that this was the beginning of our response. There will be more steps. Some of those steps will be seen. Some may not be seen. But there will be more action taken to respond to the death of the – the tragic death of the three brave U.S. service members.

Sullivan also appeared on CNN's "State of the Union" and refused to rule out attacks inside Iran:

Look, sitting on a national TV program, I'm not going to rule in and rule out any activity anywhere. What I am going to say is that the president will do what he thinks needs to be done and again, reinforce the point that he's going to defend our forces, and also that he is not looking to get into a war.

It remains to be seen whether the Biden administration's response to the violence brought by Iranian-backed groups like the Houthis will be enough to deter them from further aggression. For now at least, they remain defiant.
