Saudi Arabia's air defenses intercepted and destroyed a drone that the Saudi-led military coalition said had been launched by Yemen's Houthi movement toward the area of the holy city of Mecca, escalating tensions between the two sides amid a broader conflict in the Middle East.

Coalition spokesman Turki al-Maliki said in a statement on Wednesday that the Royal Saudi Air Defense Forces had intercepted the "hostile drone" before it entered Mecca's airspace. The coalition accused the Iran-aligned Houthi movement of being behind the launch and warned that the security of Islam's two holiest sites remained a "red line."

The Houthis, however, rejected the accusation. Hazem al-Assad, a senior Houthi figure, described the Saudi claim as a false allegation and said accusations that the movement had targeted Mecca had been made previously.

The reported incident prompted a strong reaction from the Organization of Islamic Cooperation (OIC), which represents 57 Muslim-majority countries. The organization condemned what it described as a serious violation of the sanctity of Islam's holy sites and called for measures to prevent any future attacks against them.

The incident comes as fighting along Saudi Arabia's southern border with Yemen has intensified. Houthi attacks on Saudi territory reportedly injured 13 people on Monday, with the number of people injured since the latest escalation in July reaching approximately 100, according to Saudi-linked reports.

The conflict has also affected regional maritime security. The Houthis have disrupted Saudi oil shipments through the Bab el-Mandeb Strait, an important waterway connecting the Red Sea with the Gulf of Aden and a strategic alternative route for energy exports amid disruptions around the Strait of Hormuz.

As tensions increased, Saudi Crown Prince Mohammed bin Salman held talks with Egyptian President Abdel Fattah el-Sisi on Tuesday. The two leaders discussed regional security and the importance of maintaining freedom and safety of navigation through both the Strait of Hormuz and Bab el-Mandeb.

The latest confrontation adds another layer to an already volatile regional situation involving Iran, Yemen, Saudi Arabia and other Middle Eastern actors.

The United States Embassy in Saudi Arabia also issued a security advisory on Tuesday, urging American citizens to reconsider travel to the kingdom. The advisory cited potential risks including drone and missile attacks targeting U.S. interests, armed conflict, terrorism and restrictions related to local laws and social-media activity.

While Saudi authorities say the drone was intercepted before reaching the holy city, the Houthis continue to deny responsibility for any attempted attack on Mecca. The competing claims have not been independently established in the information available.
