UK had no choice but to strike Houthis - Cameron
The UK had "no choice" but to take military action against Houthis in Yemen over their attacks in the Red Sea, the foreign secretary has said.
Lord Cameron said the UK had given the group "warning after warning" before joining US-led strikes this week.
Writing in the Sunday Telegraph, he said prices would rise in the UK if Houthis blocked important trade routes.
The pro-Hamas group have been attacking ships in the Red Sea, claiming to be targeting Israel over the war in Gaza.
Their attacks on cargo ships - some of which have no clear connection to Israel - have led major shipping companies to divert vessels away from the Red Sea, instead taking a longer route around southern Africa.
Lord Cameron said the UK took part in the strikes to defend "freedom of navigation".
He also suggested Britain could strike Houthi targets again if their attacks continued.
"If the Houthis deny this passage to ships, vital supply chains are threatened and prices will go up in Britain and across the globe," he said.
"We will work with allies. We will always defend the freedom of navigation. And, crucially, we will be prepared to back words with actions."
The Houthis are a political and military group which control a large part of Yemen, including the capital. They are backed by Iran, Israel's arch-enemy.
The Houthis have declared their support for Hamas and claim they target any ship travelling to, or owned by, Israel. They have carried out at least 27 attacks since 19 November, according to the US, and have launched a series of drones and missiles towards Israel.
But Lord Cameron said the Houthi claim that their attacks were linked to the war in Gaza was "nonsense".
"They've attacked ships from countries all over the world, heading to destinations right across the globe," he wrote.
India targets net-zero carbon emissions by 2070, says Modi
India’s economy will become carbon neutral by the year 2070, the country’s prime minster has announced at the COP26 climate crisis summit in Glasgow. The target date is two decades beyond what scientists say is needed to avert catastrophic climate impacts. India is the last of the world’s major carbon polluters to announce a net-zero target, with China saying it would reach that goal in 2060, and the United States and the European Union aiming for 2050.
COP26: What climate summit means for one woman in Bangladesh
China's carbon emissions are vast and growing, dwarfing those of other countries. Experts agree that without big reductions in China's emissions, the world cannot win the fight against climate change. In 2020, China's President Xi Jinping said his country would aim for its emissions to reach their highest point before 2030 and for carbon neutrality before 2060. His statement has now been confirmed as China's official position ahead of the COP26 global climate summit in Glasgow. But China has not said exactly how these goals will be achieved.

Deliver on promises, developing world tells rich at climate talks
A crucial U.N. conference heard calls on its first day for the world's major economies to keep their promises of financial help to address the climate crisis, while big polluters India and Brazil made new commitments to cut emissions. World leaders, environmental experts and activists all pleaded for decisive action to halt the global warming which threatens the future of the planet at the start of the two-week COP26 summit in the Scottish city of Glasgow on Monday. The task facing negotiators was made even more daunting by the failure of the Group of 20 major industrial nations to agree ambitious new commitments at the weekend.
