Following a deadly attack on Riyadh’s international airport, Yemen’s Houthi rebels issued a new threat targeting Saudi Arabia’s airspace on Sunday. The attack in Riyadh resulted in 12 fatalities and hundreds of injuries, prompting a complete halt to airport operations. This escalation marks a significant increase in hostilities between the Houthis and the Saudi-led coalition supporting the Yemeni government. The Houthis have previously claimed responsibility for similar attacks on Saudi airports and infrastructure. The Saudi government has yet to respond directly to the latest Houthi threat, but has consistently accused the group of utilizing Iran-supplied weaponry. This incident further complicates efforts towards a peaceful resolution to the ongoing conflict in Yemen. The attack underscores the continued vulnerability of civilian infrastructure in Saudi Arabia.
