My Lords, let me start by making it absolutely clear that the Houthi attacks on ships in the Red Sea and the Gulf of Aden are illegal and intolerable. Their reckless and dangerous actions threaten freedom of navigation and global trade, let alone the risk to innocent lives. That is why the UK, alongside the United States and with the support of our international partners, has carried out additional strikes on Houthi targets in Yemen in line with international law and in self-defence.

We continue to take action that is necessary, limited, legal and proportionate in terms of self-defence, freedom of navigation and protecting lives. Our aim remains to disrupt and degrade Houthi capabilities to put an end to this persistent threat, and we will not hesitate to take further appropriate action to deliver this purpose.

I turn to the specific questions raised by the noble Baronesses, which I hope will go a long way to explaining this. First, on behalf of the Government, I continue to appreciate the support from all Benches in the House; it is extremely valuable and very helpful in reaching these decisions, and, of course, we appreciate the immense professionalism of all the Armed Forces and their support who are involved in this continuing and extremely tricky situation.

The effect on commerce goes without saying. As the noble Baroness, Lady Anderson, pointed out, it is really starting to have an impact on European markets and, by definition, it must be having an impact on the manufacturing and supply bases in the Far East that ship towards Europe. On the point made by the noble Baroness, Lady Smith, about China and its silence so far on this entire issue, one can only hope that the diplomatic efforts in that direction, when tinged with a little bit of economic reality, may have a slightly more impressive effect.

As for the actual effect of the specific attacks that we have undertaken, it may be helpful to run through exactly what we are trying to do, and to delineate these specific attacks in relation to a more general approach. These carefully targeted sites—and they really are carefully targeted—are attacking deeply buried weapons storage, launch sites, ground-control systems and radars, which are the four things that will stop these attacks. The intention to deter and degrade is absolutely present, and Prosperity Guardian is all about deterrence. These three things are intricately linked. In the attack last weekend, we hit three buildings, destroyed five drones that were ready to be launched, and, as far as we are aware, no civilian casualties were caused. To date, we have had four strikes on seven facilities and 40 targets. The information is that all four have been successful in support of Prosperity Guardian and our American, and other, allies—it is the Americans, of course, who are leading.

The noble Baroness, Lady Anderson, quite rightly raises the question of Aspides, which is the EU stepping up to the plate, to some extent. To put a scale on that, it consists of four frigates and a single aerial asset. It is a defensive maritime security operation, and it will protect commercial shipping from attacks at sea or by air, but it will not involve itself in strikes on land. It started on 19 February 2024, it is based in Greece and it has an Italian force commander. It provides a valuable defensive role, but we do not see it being involved in any degrading or deterring.

On the question of the conversations with wider allies and other countries in the area, the whole purpose of the diplomatic effort is to put pressure on Iran, to try to stop the supply of weaponry to its acolytes. By taking military action—which is a final resort—as well as the diplomatic effort, we are doing all we can to restrict weapons and finance. It is consistent with our whole approach; it is appropriate and backed up with force.

My final point goes back to the question of global trade and the point that was well made by the noble Baroness, Lady Smith, that it is not just the allied shipping that is under attack. The idea that the Houthis are attacking only ships that are proving to be in support of something going on in Gaza is completely spurious. They attack whatever they like, including, as I am sure your Lordships are fully aware, the one ship that brings aid to Yemen, to support the UK and international partners. So that claim is just complete nonsense.

Finally, I will respond to the question of when these individual strikes become something more of a sustained campaign. It is a very difficult question to answer and it is not an easy one to grasp, because we do not quite know what level of effect these strikes are having on the overall capability of the Houthis. These are limited and deliberate strikes in direct response to the Houthi attacks on commercial shipping, our Navy and coalition ships in the region. There is no doubt that we have degraded the Houthi capability and we will continue to urge the Houthis, and those who enable them, to stop the illegal and unacceptable attacks on UK commercial and military vessels, and on those of our partners in the Red Sea and the wider region. Beyond that, it is very difficult to see how a broadening of this action may evolve.
