Turkey's Foreign Ministry said on the 11th it condemned a Houthi attack on Riyadh's King Khalid International Airport, calling deliberate strikes on civilian infrastructure and non-combatants a clear violation of international law and humanitarian principles. The ministry urged an immediate halt to actions that threaten regional security and undermine international peace efforts, and reaffirmed Turkey's support for Saudi sovereignty and territorial integrity.

Poland's interior ministry said police have received intelligence suggesting Prime Minister Donald Tusk and Defense Minister Wladyslaw Kosiniak-Kamysz may be targeted in the near term. The alerts follow three recent campus stabbings that killed one and injured more than a dozen. To prevent further attacks, police have inspected about 50,000 schools, are handling more than 230 suspected offense cases and have detained 76 people; some detainees allegedly carried knives, fireworks or threatened attacks. The government has increased police deployments at schools and instituted 24/7 internet monitoring. Tusk has ordered police to conduct at least one patrol of each school daily.

Houthi militants in Yemen said their warnings "should be taken seriously" and that Saudi Arabia "bears responsibility for the failed interception".
