A Houthi rebel strike on Riyadh’s international airport in Saudi Arabia resulted in 12 fatalities and over 300 injuries on Sunday. This attack represents the deadliest incident in Saudi Arabia in a decade, prompting a strong vow of retaliation from the Saudi government. Saudi Arabia has threatened a “decisive” response against Yemen’s Houthi rebels following the assault. The attack targeted a civilian airport, escalating tensions in the ongoing conflict. The Saudi-led coalition has been at war with the Houthi rebels in Yemen since 2015. This latest strike raises concerns about a further escalation of the regional conflict and potential impacts on civilian populations.
