Saudi Arabia issued an all-clear on Saturday after security alerts were sent in Riyadh and Al-Kharj.

The warnings were issued for the second time amid rising attacks by Houthi forces. Authorities later confirmed that the alerts had ended.

The warnings marked the first such alerts for Riyadh since the Houthis increased attacks against Saudi Arabia. The developments have raised fresh security concerns in the kingdom.

A Reuters journalist in Riyadh reported hearing two loud booms. The sounds were heard in the Olaya district of the capital.

There was no immediate confirmation about what caused the sounds. Authorities had not provided details about any possible damage.

The latest alerts came hours after a Houthi military spokesperson issued a statement. He claimed the group had stopped what he called “criminal attempts” in Sanaa.

The spokesperson blamed Saudi Arabia for the alleged attempts. He also warned that the group would respond to the developments.

Saudi Arabia’s government media office did not immediately comment on the statement. Officials have continued to monitor the situation amid the escalation.

The Houthis control large parts of northern Yemen. Their territory includes some of the country’s most heavily populated areas.

The group has launched attacks toward Saudi Arabia since announcing a naval blockade. The blockade was declared against the kingdom in July.

Houthi forces have also targeted vessels operating in the Red Sea. The attacks have increased concerns about regional security and maritime activity.

The group has also accused Saudi Arabia of conducting hundreds of airstrikes. The Houthis recently claimed Saudi attacks had intensified in recent days.

The developments followed a rapid Houthi advance along Yemen’s Red Sea coastline. The group recently seized control of the entire coastline, according to the report.

International concern has also grown over the continuing escalation. The United Nations Security Council issued a statement on Friday.

The council condemned what it described as continued Houthi attacks against Saudi Arabia. It said some strikes affected civilian and energy infrastructure.

According to the council, civilians were injured in the attacks. Women and children were among those reportedly affected.

The Security Council also condemned the Houthis’ military escalation inside Yemen. It called attention to the wider security situation in the region.

The latest alerts have added to concerns about the potential impact of the conflict. Saudi authorities issued the all-clear after the warnings were triggered.

The alerts and subsequent all-clear remain part of a wider regional security situation. Officials are continuing to monitor developments involving Saudi Arabia and Yemen.

The situation remains fluid as both sides exchange accusations. Further security measures could depend on developments in the coming days.
