Saudi Arabia is weighing different options to deal with the Houthis, who are escalating their threats against the kingdom in a sign officials and analysts say could forebode a return to fighting in Yemen.

The kingdom’s defence minister, Khalid bin Salman, has suggested that the US is giving Saudi Arabia leeway to pursue offensive strikes against the Houthis, multiple US and regional officials told Middle East Eye. However, its leadership has not made a decision.

One US and one western official said the discussions could point to differences of opinion within the Saudi royal court over how to respond to the Houthi threat as wider fighting between the US and Iran escalates.

The discussions come as a four-year ceasefire between Saudi Arabia and the Houthis is tested by a recent exchange of fighting.

The Houthis inflamed tensions with Saudi Arabia earlier this month after a flight arrived at Sanaa airport to carry Houthi officials to the funeral of assassinated Iranian Supreme Leader Ayatollah Ali Khamenei.
