One of Saudi Arabia’s most iconic skyscrapers ordered office workers to stay home Sunday as escalating attacks by Iran-backed Houthi rebels rattled the capital of Riyadh amid fears of a widening Middle East conflict.
The move came after the Houthis disrupted the Saudi capital.
The security concerns also follow a deadly Oct. 10 attack on King Khalid International Airport that killed 13 people and wounded more than 300 others.
As previously reported by Fox News Digital, another strike the following day killed one person and injured 11.
Airport operations have been severely disrupted, while schools in Riyadh have extended remote learning measures amid continued security threats.
The mounting crisis comes as Saudi Arabia's military reported two deaths in a helicopter crash near its southern border with Yemen.
Maj. Gen. Turki al-Maliki, spokesperson for the Saudi-led coalition, said Sunday that an AH-6i reconnaissance helicopter crashed in the Najran region because of a technical malfunction, killing both crew members.
Saudi civil defense authorities also reported Sunday that six people were injured when a hostile projectile struck a residential neighborhood in Najran, damaging three homes and three vehicles.
Meanwhile, Egypt moved toward potentially providing military assistance to Saudi Arabia as the kingdom confronts the growing Houthi threat.
Egyptian President Abdel Fattah el-Sissi requested an emergency parliamentary session to authorize defensive military support for Saudi Arabia if requested by Riyadh, regional response to the Houthis.
The Iran-backed group now controls Yemen's capital, Sanaa, and much of the country's north.
Fighting with the Saudi-led coalition, which supports Yemen's internationally recognized government, has intensified amid the broader U.S.-Israeli conflict with Iran.
