Saudi officials say interceptor missiles are running low as Houthi attacks intensify, while Crown Prince Mohammed bin Salman moves between guarded palaces

Saudi Arabia is running low on air-defense interceptor missiles as attacks by Yemen’s Houthis intensify, according to Saudi officials cited by The Wall Street Journal. The report says Crown Prince Mohammed bin Salman is moving cautiously between heavily guarded palaces equipped with bunkers, accompanied by handpicked security guards.

The kingdom is struggling to defend its energy infrastructure and royal residences while covering its vast territory, the Journal reported. Saudi Arabia has been repositioning missile-defense batteries to protect those sites.

In September, The Associated Press reported that Saudi Arabia had sought air-defense support from France, Britain, Pakistan and Egypt as it faced a shortage of interceptors, citing two regional officials.
