The European Union and Gulf states on Thursday postponed ​a joint summit due to be held in ‌Saudi Arabia next week, as sustained attacks by the Iran-aligned Houthis fuel concerns about air travel to and from the kingdom.

Axar.az reports, citing Reuters, that the Gulf ​Cooperation Council cited continued Houthi threats against Saudi ​Arabia and an extended suspension of operations at ⁠King Khalid International Airport when announcing the postponement of ​the summit scheduled for October 24 in Riyadh.

The EU did ​not specify a reason for the delay, saying only that a new date would be announced "in due course".

The postponement is the latest ​blow to Saudi Arabia's effort to host global events ​despite the escalating war with the Houthis.
