Where did the strikes happen? The US said more than 60 targets were hit at 16 locations, including “command and control nodes, munitions depots, launching systems, production facilities, and air defence radar systems”. The Houthis have said there were 72 strikes in all. The US said more than 100 precision-guided munitions of various types were used in its strikes, including Tomahawk land-to-air missiles. The UK said it targeted two locations: a site at Bani Basrah, which the UK says was used to launch reconnaissance and attack drones, and an airfield at Abs. The US has not given location details of where it struck, but accounts have emerged from the Houthis and other sources.

The Ministry of Defence said the UK used four RAF Typhoon FGR4s, supported by a Voyager air refuelling tanker. The aircraft flew from RAF Akrotiri in Cyprus at roughly 7.30pm UK time on Thursday and dropped their payload on the Yemeni sites at about 11.30pm. They had returned to Cyprus by 3am. This map shows the Cyprus base and the location of the strikes: The fighter jets used Paveway IV guided bombs. This footage released by the MOD shows the two strikes: Why have the US and UK attacked the Houthis? The strikes are in response to Houthi attacks on commercial carriers in the Red Sea that the US and UK have said threaten the free passage of goods through the region, which in turn could destabilise the global economy. The Houthis say their Red Sea attacks are in support of Hamas in its war with Israel in Gaza. Who are the Houthis? The Houthis are a Yemeni militia group named after their founder, Hussein Badreddin al-Houthi, and representing the Zaidi branch of Shia Islam. They emerged in the 1980s in opposition to Saudi Arabia’s religious influence in Yemen. The group, which has an estimated 20,000 fighters and whose official name is Ansar Allah, runs most of the west of the country and is in charge of its Red Sea coastline. How has the group responded? The Houthis said five of their fighters had been killed, and vowed to retaliate and continue their attacks on shipping. Footage aired on the Houthis’ al-Masirah TV on Friday afternoon showed hundreds of thousands of people carrying Palestinian and Yemeni flags. The crowd chanted slogans denouncing Israel and the US in response to messages broadcast from a speaker:
