It's been a busy few hours for our teams in London and Washington, following the US strike development in Yemen.
If you're just joining us, here is what's been happening:
The US carried out a fresh attack on the Houthi group in Yemen, after the Iran-backed militants warned of further attacks on ships in the Red Sea
The US military said an American destroyer, the USS Carney launched Tomahawk cruise missiles against a radar site in Yemen
This follows Friday's wider US-UK strikes, which targeted nearly 30 locations
The Yemeni group's leader promised to take revenge on the US and Britain for the strikes
UN chief Antonio Guterres has called on all sides "not to escalate" in the interest of regional peace and stability
Biden calls strikes a success - what the Houthis do next will show whether he is right

BBC News, Washington
The US Central Command suggested
this Houthi radar station was not a new target – in the statement, the strike
was described as a "follow-on action" after the previous night’s
attacks.
Hours earlier, President Biden
had warned the US would respond if the Houthis continued what he called their "outrageous
behaviour".
These fresh strikes are unlikely
to result in any significant escalation in the region – this was clearly
nowhere near on the same scale as the coordinated strikes on Thursday night,
when around 30 Houthi-controlled sites were targeted by US-led forces.
President Biden has called the
military action "a success".
But what the Houthis do next - and
whether the US and its allies take any further action - will show whether Biden
is right.
'This was to send a message to the Houthis'

A retired US colonel has been talking to the BBC about the likely US
goals with its missile attacks on Yemen.
Colonel Brendan Kearney says the strikes were probably designed to "send a message" to
the Houthis for their failure to listen to the warnings that "have been
given to them".
He adds that if the group start firing missiles at maritime
shipping then they'll be "a new round of attacks on Yemen".

As a reminder, US and UK jets and warships launched dozens of airstrikes across Yemen against Houthi sites.
UK PM Rishi Sunak has said it was done "in self-defence" after months of attacks on Red Sea shipping.

Dr Elisabeth Kendall, a specialist on Yemen at Cambridge University, says "we should not imagine that the Houthis operate entirely by logic".
Dr Kendall, speaking before news of the latest US strike on Yemen's capital, told BBC Radio 4's The Briefing Room on Friday: "They really do believe that God is on their side... there's emotion and religious belief that needs to come into this equation."
Dr Kendall also said the relationship between the Houthis and Iran exists because their interests align.
The Houthi movement was formed in the 1990s to combat what they saw as the corruption of the then-president of Yemen, Ali Abdullah Saleh. Since 2014, they have been fighting a civil war against the government.
Iran is suspected of supplying the Houthis with weapons but has denied involvement in the Red Sea attacks.
What are Tomahawk missiles?

Tomahawks are land attack cruise missiles which are GPS-guided and can be programmed to fly evasively, the US military says.
They are long-range and primarily used by the US Navy and Royal Navy in ship and submarine-based land-attack operations.
They are designed to fly at extremely low altitudes at high subsonic speeds, according to the US Naval Air Systems Command.
The first operational use from the US was during Operation Desert Storm in the Gulf War in 1991.
BreakingUS military confirms strike with Tomahawk missiles on radar site
We've just been hearing from the US military, which has confirmed it conducted a strike against a Houthi radar site in Yemen.
The radar site was hit by Tomahawk missiles, the military said in a statement.
It was a "follow-on action" on a specific military target associated with strikes taken on 12 January and designed to "degrade the Houthi’s ability to attack maritime vessels, including commercial vessels", the statement added.

Ships diverting from the Red Sea
As we've previously reported, major shipping firms have been diverting their cargo away from the Red Sea ever since the Houthis first launched their attacks.
These images compare the movements
of container ships in November, just after the first attack on a commercial vessel, with the situation today.
You can see how many ships are
now taking the longer route around southern Africa's Cape of Good Hope.

There has been less of a reduction in oil and gas tankers using the Red Sea route, according to data from the Marine Traffic website, but the International Association of Independent Tanker Owners (Intertanko) has advised shipping to avoid passing through the area if possible, and to turn off their transmitters if they do so.
It’s also interesting to note that some ships passing the Yemen coast are listing no destination, or “no contact with Israel”. Others are declaring “armed guards on board”.
What we know about latest strike
Details are still emerging of the latest US strike against the Houthis in Yemen.
A Houthi-run TV channel Al-Masirah is reporting that Yemen's capital Sanaa, which is held by Houthi rebels, has been targeted.
"The American-British enemy is targeting the capital, Sanaa, with a number of raids," the channel posted on X, formerly Twitter, citing its correspondent in the city.
Associated Press journalists in Sanaa heard one loud explosion.
Second strike 'carried out from Navy ship'
NBC and AP are also reporting the new strike in Yemen.
It was carried out by the US from a Navy ship, one unnamed official told NBC.
Two officials told AP the US targeted a radar site that was still determined to present a threat to maritime traffic.
The BBC is chasing confirmation of this from the Pentagon.
It comes a day after the US and UK targeted nearly 30 Houthi locations in retaliation for the Yemeni rebels attacking vessels in the Red Sea.
BreakingUS reportedly launches another air strike in Yemen
The US is carrying out another strike against Houthis in Yemen, according to American media.
CNN and Reuters news agency are quoting unnamed US officials.
It comes minutes after the Houthi TV channel Al-Masirah reported early on Saturday that raids had targeted the country's capital Sanaa.

UK Defence Secretary Grant Shapps has called on Iran to urge its allies to "cease and desist" after the UK and US launched airstrikes against the Houthi rebels in Yemen.
He called for it to be "clearer with its many proxies" in the Middle East.
"You must get the Houthi rebels," he said, "others who are acting as proxies for you, Lebanese Hezbollah are obvious examples, some in Iraq and Syria, you must get these different organisations to cease and desist.
"We see you, we see through what you're doing. We see how you're doing it, particularly the Houthi rebels, and no good can come from it."
Biden 'very concerned' about oil prices

Joe Biden also said in Allentown, Pennsylvania, that he is "very concerned" about the impact the war in the Middle East will have on oil prices.
Oil rose by 1% on Friday after the UK and US launched dozens of air strikes across Yemen on Houthi targets and a number of oil tankers diverted course from the Red Sea.
After speaking of his concern around rising oil prices, Biden added: "That's why we got to stop it."
Inflation and petrol/oil prices may be key issues during this year's presidential election.

The UK and US have defended their action to carry out strikes against the Houthis in retaliation for the Yemeni rebel group's attacks on ships in the Red Sea and the Gulf of Aden.
Both have said the strikes are legal under international military law.
US Ambassador to the UN Linda Thomas-Greenfield told the UN Security Council the strikes were "to disrupt and degrade the Houthis' ability to continue the reckless attacks against vessels and commercial shipping".
She added more than 2,000 ships had been forced by the Houthi attacks to divert from the Red Sea since November.
Prime Minister Rishi Sunak has insisted the UK and US acted "in self-defence" and that allies would not hesitate to ensure the safety of commercial shipping.

With the US now embroiled in three theatres of conflict from the Middle East to Ukraine, the head of the Pentagon has been facing calls to resign after he failed to disclose his serious illness.
The White House says Joe Biden only learnt of Defence Secretary Lloyd Austin's prostate cancer diagnosis just before he made it public on Wednesday.
The president was asked on Friday by reporters if he remained confident in Austin's leadership, to which Biden replied: "I do".
The top cabinet member, aged 70, did not disclose a hospital visit in late December, for which he had surgery to treat his condition. Neither did he notify the White House about his admission to intensive care on New Year's Day to treat complications from the procedure.
According to the Pentagon and White House, Austin continued to carry out his duties from his hospital bed as the US and UK launched military strikes against the Houthi rebel group in Yemen.
Maj Gen Pat Ryder, a Pentagon spokesperson, told BBC News that Austin "gave the order to the US Central Command commander to go ahead and execute the strikes".

The Houthis have vowed that the strikes by the US and UK will not go without "punishment or retaliation" and they will continue attacking ships in the Red Sea

The Pentagon's press secretary has just spoken to the BBC.
Maj Gen Patrick Ryder said the US does not want to see an "extension of the conflict in Gaza, broader into the region, and we'll continue to work hard on that".
He added that, at the same time, the US "can't allow the Houthis to continue to conduct these attacks".
