A missile attack on Saudi Arabia's King Khalid International Airport in Riyadh killed at least 12 people and injured over 300, according to Saudi civil aviation officials. The strike, which occurred on Saturday, has prompted the country to extend the closure of its main international airport. The attack is being attributed to Yemen's Iran-backed Houthis, according to a diplomatic source.

The airport, a key hub for international travel, was hit by a missile that caused significant damage. The casualties include individuals from multiple countries. Saudi authorities have not yet confirmed the exact number of fatalities or the full extent of injuries. The attack marks a major escalation in the ongoing conflict between Saudi Arabia and the Houthis.

This is the third such attack on the airport in less than a week. The conflict between Saudi Arabia and the Houthis, supported by Iran, has intensified in recent months. The Saudi-led coalition has been conducting military operations in Yemen since 2015. The Houthis have repeatedly targeted Saudi infrastructure, including oil facilities and airports, as part of their broader campaign.

The attack has raised concerns about the safety of air travel and the stability of the region. Saudi Arabia has warned of a strong response to the attack. The situation highlights the ongoing tensions between regional powers and the humanitarian impact of the conflict.
