Following the attack on King Khalid International Airport in Riyadh, the Saudi-led Arab coalition announced that a decisive response would be carried out.
Major General Turki al-Maliki, spokesperson for the coalition supporting Yemen's government, said one of the airport's passenger terminals was targeted in an attack attributed to the Houthis in Yemen. Al-Maliki said that civilians and airport employees were among those killed and injured.
Saudi Arabia's General Authority of Civil Aviation said the death toll from the attack had risen to 12 and the number of injured to 309.

Al-Maliki argued that the attack constituted a clear war crime under international humanitarian law and the customary rules of international law. The coalition spokesperson also said the attack was incompatible with humanitarian principles, values and moral norms.
It was announced that the Joint Forces Command would deliver a decisive response to the attack within the framework of international humanitarian law and applicable rules.
Earlier statement put death toll at 4
In a statement issued on October 10, the General Authority of Civil Aviation said that four people had been killed and many others injured in Houthi attacks on King Khalid International Airport between October 6 and 8.

Fighting continues in Yemen
Fighting between government forces and the Houthis in Yemen has intensified in recent months. The Iran-backed Houthis maintain that they have come under attack and have carried out attacks on Saudi Arabia using ballistic missiles and unmanned aerial vehicles.
The country's civil war began after the Houthis seized control of the capital, Sana'a, and several provinces in September 2014. The Saudi-led Arab coalition has supported Yemen's internationally recognized government since March 2015.
