U.S. forces on June 1 destroyed one Iran-backed Houthi uncrewed aerial system in the southern Red Sea and saw two others crash into Red Sea, U.S. Central Command said.

The Central Command forces also destroyed two Houthi anti-ship ballistic missiles fired in direction of the USS Gravely, it said. No injuries or damage were reported by U.S., coalition or commercial ships, it said.

Sanaa:

Yemen’s Houthi rebels say that they have launched a missile strike on a United States aircraft carrier in the Red Sea in retaliation for recent deadly strikes by the US and UK in Yemen, Al Jazeera reported.

Houthi military spokesperson Yahya Saree announced the attack on the Eisenhower carrier on Friday, following earlier claims by the group that at least 16 people were killed in US and UK assaults on Yemen’s Hodeidah province. This marks the highest publicly acknowledged death count from multiple rounds of strikes linked to the group’s alleged assaults on shipping.

Al Masirah television, a Houthi-controlled channel, broadcasted footage showing wounded civilians being treated in Hodeidah, revealing the fallout from Thursday’s attacks. At least 42 people were reported injured.

“The American-British aggression will not prevent us from continuing our military operations in support of Palestine,” Houthi official Mohammed al-Bukhaiti said on X, warning that the rebels would “meet escalation with escalation”.

The US Central Command (CENTCOM) reported that attacks on 13 Houthi targets resulted in the destruction of eight uncrewed aerial vehicles (UAVs) in Houthi-controlled areas of Yemen and over the Red Sea, according to Al Jazeera.

Meanwhile, the British Ministry of Defence stated that Royal Air Force Typhoon FGR4s conducted strikes on Hodeidah and Ghulayfiqah. It described targets as “buildings identified as housing drone ground control facilities and providing storage for very long-range drones, as well as surface-to-air weapons”.

British Prime Minister Rishi Sunak defended the military action as a form of “self-defence in the face of an ongoing threat that the Houthis pose”.

The Houthi movement, aligned with Iran, controls significant portions of Yemen after nearly a decade of conflict against a Western-backed and Saudi-led coalition. They have vocally supported Palestinians amid Israel’s ongoing conflict in Gaza, launching repeated drone and missile attacks on ships in the Red Sea, Bab al-Mandeb strait, and the Gulf of Aden since November.

Iran condemned the US-UK strikes as “violations of Yemen’s sovereignty and territorial integrity … international laws and human rights”, Al Jazeera reported, citing, Iranian state media.

“The aggressor US and British governments are responsible for the consequences of these crimes against the Yemeni people,” Iranian foreign ministry spokesperson Nasser Kanaani said.

According to the US Maritime Administration, Houthis have launched over 50 attacks on shipping, resulting in casualties, vessel seizures, and disruptions to global trade routes. The campaign has forced shipping firms to seek alternative routes, impacting approximately 12 per cent of global trade that traverses the Red Sea.

Despite retaliatory strikes by the US and UK aimed at degrading Houthi capabilities, the rebels have continued their assaults. In their latest actions, they targeted a Greek-owned bulk carrier and other vessels in response to Israeli strikes on Gaza, Al Jazeera reported.

Eilat, Israel:

The Red Sea’s spectacular coral reefs face a new threat, marine biologists warn — the mass death of sea urchins that may be caused by a mystery disease.

Because the long-spined creatures feed on algae that can suffocate corals, their die-off could “destroy our entire coral reef ecosystem”, warned scientist Lisa-Maria Schmidt.

In Israel’s Red Sea resort of Eilat, which borders Jordan and Egypt, Schmidt recalled the moment she and her colleagues first witnessed the population collapse.

“When we jumped into the water, all of a sudden all those specimens we used to see before were gone, and what we saw was skeletons and piles of spines,” she told AFP.

The team had first heard reports in January that a sea urchin species off Eilat was dying rapidly, so they went to a site known for an abundance of the species Diadema setosum.

They first thought that local pollution could be to blame.

But, within two weeks, the spiny invertebrates also started dying down the coast, including in a seawater-fed facility of the Inter-University Institute for Marine Sciences.

Scrambling to find the cause, the scientists watched with growing alarm as the mass mortality spread south through the Red Sea.

The team found that it affected two kinds of sea urchin, Diadema setosum and Echinothrix calamaris, while other species in the same environment remained unharmed.

In the marine reserve off Eilat, colourful fish and some other sea urchin species could be seen by a visiting AFP journalist — although the impact of humans was never far away.

While snorkelling, Schmidt grabbed floating plastic rubbish and pushed it up the sleeve of her wetsuit, to discard later.

Walking along the beach, she also picked up handfuls of algae, to feed to the sea urchins still alive in tanks.

‘Absolutely devastating’

A similar mass mortality earlier hit sea urchins in the Caribbean, raising speculation that a disease may have arrived in the Red Sea by ships, whose ballast water can carry pathogens and exotic species.

“I think it’s especially scary for that region, especially in the Red Sea,” said Mya Breitbart, a biologist from the University of South Florida in the United States.

She pointed out that, while coral reefs are dying off in many other areas, “those corals are known to be quite resilient, and I think people have placed a lot of hope in those reefs”.

Early last year, Breitbart started hearing that the Diadema antillarum species — similar to those affected in the Red Sea — was rapidly changing behaviour and then dying in droves in the Caribbean.

The area has still not recovered from a similar event in the 1980s, whose cause was never discovered, and Breitbart described this second die-off there as “absolutely devastating”.

Within months she and scientists working across the Caribbean had pinpointed a pathogen, giving hope that the cause of the Red Sea die-off could be discovered.

Next disease ‘on the way’

Omri Bronstein, from the University of Tel Aviv, has been working with the team in Eilat and elsewhere to try and identify the source.

“Are we talking about the same pathogen, for example, as the one that hit the Caribbean” in the 1980s, asked Bronstein, who runs a laboratory at the university where sea urchins lie in glass jars.

“Or are we looking at a completely different scenario?”

Stopping the die-off in the seas is impossible, lamented Bronstein.

Instead, the scientific community is working towards establishing a broodstock population of the affected species which can be released into the Red Sea once the current threat has passed.

Once the cause has been identified, Bronstein and his colleagues will also seek to determine how it reached the Red Sea.

If it was transported by a vessel, for example, steps could be taken to clean up ships and minimise the risk of spreading the next deadly pathogen.

“This is something that we can fix, because the next disease is on the way,” he said.

“It is probably in one harbour and in one of the ships that is currently sailing our oceans.”
