Saudi Arabia Shuts Riyadh Airport Until October 17 After Attacks: Why Houthi Missiles Are Getting Through

(MENAFN- Live Mint) Saudi Arabia has extended the closure of Riyadh's King Khalid International Airport until October 17 after deadly attacks blamed on Yemen's Houthi rebels disrupted flights and raised questions about the kingdom's ability to defend critical infrastructure.

The airport has been shut since Saturday's attack, which reportedly killed 13 people and wounded more than 300.

A further attack on Sunday killed one person and injured nearly a dozen others.

Quick answers to key questions

.5 QUESTIONS1Why was Riyadh's King Khalid International Airport closed until October 17?⌵

Saudi authorities extended the closure after deadly attacks attributed to the Houthis killed and injured people and disrupted airport operations. Terminals, radar and communications equipment were also reported damaged.

2How did Houthi missiles get through Saudi air defences?⌵

An initial investigation indicates that multiple drones may have preceded cruise and ballistic missiles, complicating detection and response. The precise sequence and reasons the weapons reached their targets remain under investigation.

3Why can Saudi air defences struggle to stop repeated Houthi attacks?⌵

Drones, cruise missiles and ballistic missiles have different speeds and flight profiles, making simultaneous threats difficult to track and intercept. Limited interceptor supplies and the challenge of defending a vast territory add pressure.

4How did the Riyadh airport attacks affect flights in Saudi Arabia?⌵

Aircraft avoided Riyadh while the airport was closed, and flights were diverted or cancelled. Flights continued to land at Jeddah, while cancellations across Saudi airports reached 46.4%, according to figures cited in the article.

5Should travelers fly through Saudi airspace after the Riyadh airport attacks?⌵

The articles report aviation warnings about flying over parts of Saudi Arabia and advise passengers to consult their governments' travel guidance. An airline's decision to operate a route is not, by itself, a guarantee that it is safe.

The strikes have highlighted the growing capabilities of the Houthis ' missile and drone arsenal and the challenges facing Saudi Arabia despite its advanced air defence systems, as attacks reach deep inside Saudi territory.

Why are the Houthis targeting Saudi Arabia?

The Houthis, an Iran-backed movement that seized Yemen's capital, Sanaa, in 2014, have expanded their military capabilities over the past decade. Their drones and missiles have reached targets as far away as Israel, while repeated cross-border attacks have threatened Saudi territory and infrastructure.

Saudi Arabia's airports are strategically important, connecting the kingdom to international travel, trade and commerce. Riyadh is a major political and economic centre, making attacks on its transport infrastructure particularly disruptive.

The attacks come amid wider regional tensions that have also threatened shipping routes and energy supplies. The Bab al-Manda strait, which connects the Red Sea to the Gulf of Aden, is a key route for global trade and energy shipments.

Further escalation involving the Houthis could add to regional security and shipping at risks amid the Hormuz crisis.

How are Houthi missiles getting through Saudi air defences?

An initial investigation into the Riyadh airport attack indicates that the Houthis used multiple drones before launching a combination of cruise and ballistic missiles, according to two regional officials cited by the Associated Press.

The drones may have helped pave the way for the missiles, complicating the task of Saudi air defence systems. One official cited by AP said investigators were also examining why the systems did not provide earlier warning of the attack, in which the weapons travelled more than 1,000 kilometres (621 miles) to reach Riyadh.

The Houthis possess ballistic missiles and systems capable of changing direction during flight, which can make interception more difficult. The precise sequence of events and reasons the weapons reached their targets remain under investigation.

Saudi Arabia operates advanced, multilayered air defence systems, including US-supplied Patriot and THAAD systems.

However, several factors can complicate efforts to stop sustained attacks.

Mixed attacks can overwhelm defences: Drones, cruise missiles and ballistic missiles have different flight profiles and speeds. Detecting, tracking and responding to several types of threats at once can place pressure on air defence networks. Interceptor supplies are limited: Patriot and THAAD interceptors are expensive and take time to replenish. The wider regional conflict has placed additional pressure on air defence stocks, raising concerns about how long countries can sustain protection against repeated attacks. Defending a large territory is difficult: Saudi Arabia must protect cities, airports, military installations and energy facilities across a vast area.

An aviation source who oversees Gulf flights told AFP that Saudi authorities had informed airlines the suspension would last at least until Thursday.

The source cited in the report also said terminals 3 and 4, radar and communications equipment had been damaged.

The airport's closure has since been extended until October 17.

Flight-tracking data from Flightradar24 showed aircraft avoiding Riyadh on Monday, although flights continued to cross Saudi airspace and land at Jeddah, a major aviation hub on the kingdom's western coast.

Cancellations across Saudi airports reached 46.4%, according to aviation analytics firm Cirium cited by Reuters.

“This level of sustained intense attack on civil aviation is unprecedented,” Mark Zee, founder of aviation safety advisory group OPSGROUP, told Reuters.

Saudi Arabia has reportedly approached friendly countries for air defence deployments and other assistance.
