In recent months Saudi Arabia recorded a dozen weekly attacks with ballistic rockets and drones. The perpetrators are the Houthi guerrillas deployed in Yemen, who accuse them of having formed an alliance with the government in Sana'a. In any case, Riyadh has repelled most of the raids thanks to its American-made Patriot surface-to-air anti-missile system. However, its arsenal of interceptor missiles is now reportedly running low.

This is what emerges from a statement by Saudi and US officials. That is why Riyadh would be urgently appealing to the United States, its Gulf and European allies to receive a supply of rockets as soon as possible. However, the US Senate has already said no to the sale of 280 air-to-air missiles to Saudi Arabia, after President Joe Biden's recent objections. 

In Riyadh there is concern because in January the Houthi hitted buildings belonging to the royal court, without causing any injuries. American officials seemed ready to formally approve the Saudi request, despite concerns about human rights in Saudi Arabia and other issues. Let's see if Washington will confirm aid to the ally.
