Yemeni forces have launched drone attacks on King Khalid Air Base in Saudi Arabia’s southwestern province of Asir in retaliation against the kingdom’s aggression on their country.

The spokesman for Yemeni Armed Forces, Brigadier General Yahya Saree, said several Qasef-K2 (Striker-K2) combat drones had targeted the air base near the city of Khamis Mushait on Tuesday morning, hitting radars and other military positions.

“The drones hit the designated targets with high precision,” he said.

Saree added that the attacks were in response to the Saudi crimes and the kingdom’s continued airstrikes on Yemen, noting that Riyadh had conducted 23 air raids on the country in the past 24 hours.

The Tuesday attacks on King Khalid Air Base were the fourth of their kind since mid-July.

Saudi Arabia and a number of its regional allies launched a brutal war against Yemen in March 2015.

The US-based Armed Conflict Location and Event Data Project (ACLED), a nonprofit conflict-research organization, estimates that the Saudi-led war has claimed the lives of over 60,000 Yemenis since January 2016.

The war has also taken a heavy toll on the country’s infrastructure, destroying hospitals, schools, and factories. The United Nations (UN) says over 24 million Yemenis are in dire need of humanitarian aid, including 10 million suffering from extreme levels of hunger.
