The group launched a missile towards Riyadh's main airport on Saturday, which Saudi Arabia said was a declaration of war by Tehran.
But after years of fighting that have ravaged the deeply poor country with hunger and disease, even some of Saudi Arabia's staunchest allies in Yemen say they are angry at being manipulated from abroad.At a hospital in the Yemeni city of Marib, demand for artificial limbs from victims of the country's war is so high that prosthetics are made on site in a special workshop.
A soldier with an artificial arm hitches up his robe to reveal a stump where his leg once was. He is angry that authorities have done little to help him since he was wounded.
"I was at the front and a mortar exploded near me. We fought well, but now I get no salary, no support from the government or anyone. They just left us," said Hassan Meigan.
More than two years into a war that has already left 10,000 dead, regional power Saudi Arabia is struggling to pull together an effective local military force to defeat the Iranian-aligned Houthi movement that has seized large parts of Yemen.
The dysfunction is a reminder to Saudi Crown Prince Mohammed bin Salman that his campaign to counter arch-enemy Iran in the Middle East, including threats against Tehran's ally Hezbollah, may be hard to implement.
During a rare visit to a large area of Yemeni territory controlled by the pro-Saudi government, journalists saw a patchwork of mutually suspicious army units, whose loyalty to disparate regions and commanders has hindered their war against Houthi fighters.
Some soldiers appeared to be hunkering down in their bases rather than joining the fight. Those who do fight say salaries go unpaid for months. The front lines have barely moved for months.
Saudi Arabia has sought to create a unified military force based in Marib, but these troops have failed to eject the Houthis from the nearby capital Sanaa, where the Saudis see the rebels as a threat to their national security.
With Saudi politics in turmoil after a wave of high-profile arrests and Iranian influence growing, Yemeni officers recognise the importance of an effective army but acknowledge that success still eludes them.
A coalition spokesman, Colonel Turki al-Malki, said in September that the mission was to back Yemen "whether it's inside the country by supporting the Yemeni National Army or defending the borders and territory of the Kingdom of Saudi Arabia."
Sunni Saudi Arabia has led the mostly Gulf Arab coalition against the Shi'ite Houthis, since they seized the Yemeni capital and fanned out across the country.
But the Houthis' rump state in Yemen's Western highlands has weathered thousands of Saudi-led air strikes that have been aided by refuelling and intelligence from the United States.
Denying they are a pawn of Iran, the Houthis say they are fighting to fend off a mercenary army in the thrall of the Gulf and the West.
