RIYADH, October 11: Countries and international organisations have strongly condemned deadly Houthi attacks on Saudi Arabia, including a missile strike on King Khalid International Airport in Riyadh that killed at least 12 people and injured 309 others, according to Saudi authorities.

The victims included four Saudi nationals, two Bangladeshis and citizens of the United States, Jordan, Palestine, Syria, Sudan and Egypt.

The attack on Saturday marked the third strike on Riyadh’s international airport within a week, raising concerns over civilian safety and regional security.

US President Donald Trump condemned the attack, describing it as “terrible”, and said Washington was considering whether to join Saudi Arabia’s military campaign against the Houthis.

US Secretary of State Marco Rubio also denounced the strikes, expressing solidarity with Saudi Arabia and offering condolences to the victims’ families.

UN Special Envoy for Yemen Hans Grundberg warned that attacks on civilian airports represented a grave escalation, threatening regional security and undermining peace efforts.

Bahrain, Qatar, Jordan, Egypt, Oman and several other countries also condemned the attacks, expressing solidarity with Riyadh and calling for measures to protect civilians and prevent further escalation.

Saudi authorities temporarily suspended operations at King Khalid International Airport following Saturday’s strike, while numerous flights were cancelled or diverted.

The attacks come amid escalating fighting in Yemen, where Saudi-backed government forces are battling the Iran-aligned Houthi group.

Saudi Arabia has launched airstrikes in support of the internationally recognised Yemeni government.

The latest violence has intensified fears of a wider regional conflict and renewed international calls to protect civilian infrastructure and pursue diplomatic solutions.
