US air strikes hit Houthi-controlled areas of Yemen overnight, including the capital Sanaa, the Pentagon and Houthi-run media said on Sunday.
American warplanes staged strikes on Saturday night against advanced weapons storage facilities operated by the Iran-backed group, the Pentagon told AFP.
The sites "contained various weapons used to target military and civilian vessels navigating international waters throughout the Red Sea and Gulf of Aden", according to information provided by the Pentagon.
The Houthi-run Al Masirah news outlet reported at least nine "American and British raids" across the capital Sanaa, its suburbs and Amran governorate in the north-west of the country.
There were no immediate reports of casualties and no comment from British authorities.
The US and UK have repeatedly attacked Houthi-controlled areas in response to the group's assaults on Red Sea shipping over the war in Gaza. Last month, US Defence Secretary Lloyd Austin said stealth bomber jets had hit underground storage facilities. Washington could hit targets "no matter how deeply buried underground, hardened or fortified”, he said.
Attacks on vessels in the Red Sea and Gulf of Aden, which the Houthis say target ships connected to or travelling to Israel, have caused major disruption to global trade and prompted the EU to kick-start a regional naval mission to counter the strikes.
The Houthis have also fired drones at Tel Aviv, killing one person in an attack in July.
The latest US offensive came as the Houthis claimed to have shot down 12 MQ-9 US Reaper drones over the past year, saying the surge in downed drones "has led to significant embarrassment and questions about the transparency of the US military’s response".
Washington previously confirmed some of its Reaper drones, worth approximately $30 million each, have been shot down by Houthi surface-to-air missiles.
Israel has also launched several strikes on Houthi-controlled areas of Yemen, including deadly attacks on the vital Hodeidah port – a lifeline for a country enduring one of the world's most severe humanitarian crises.
Haemoglobin disorders explained
Thalassaemia is part of a family of genetic conditions affecting the blood known as haemoglobin disorders.
Haemoglobin is a substance in the red blood cells that carries oxygen and a lack of it triggers anemia, leaving patients very weak, short of breath and pale.
The most severe type of the condition is typically inherited when both parents are carriers. Those patients often require regular blood transfusions - about 450 of the UAE's 2,000 thalassaemia patients - though frequent transfusions can lead to too much iron in the body and heart and liver problems.
The condition mainly affects people of Mediterranean, South Asian, South-East Asian and Middle Eastern origin. Saudi Arabia recorded 45,892 cases of carriers between 2004 and 2014.
A World Health Organisation study estimated that globally there are at least 950,000 'new carrier couples' every year and annually there are 1.33 million at-risk pregnancies.
The burning issue
The internal combustion engine is facing a watershed moment – major manufacturer Volvo is to stop producing petroleum-powered vehicles by 2021 and countries in Europe, including the UK, have vowed to ban their sale before 2040.
