Houthis kill 14 at Saudi airport as expert warns of 'rapid targets' amid Middle East war

Iran-backed Houthis launched a series of attacks on Saudi Arabian airports through Sunday, reportedly killing at least 14 people, including an American, and injuring more than 300 others, according to reports .

The attacks heightened fears of a wider Middle East war as regional experts warned of "cross-domain escalation" amid heightened tensions over Washington's September actions against Iran's aviation sector.

The Houthis claimed responsibility for earlier attacks on King Khalid International Airport in Riyadh, while U.S. officials blamed the Iran-backed group for Saturday's strike, which reportedly killed 13 people and injured more than 300.

Meanwhile, an airport in Dammam, in the kingdom's Eastern Province, was also reportedly targeted by the Houthis.

"Cross-domain escalation by Iran and its proxies will continue to be a primary strategy," Behnam Ben Taleblu , senior director of the Iran Program and a senior fellow at the Foundation for Defense of Democracies, told Fox News Digital on Sunday.

"The emphasis on aviation targets connects directly to the closing of Iran's aviation sector and sanctions imposed on its commercial airlines under the U.S. maximum pressure campaign," he warned.

Secretary of State Marco Rubio condemned Saturday's attack, confirming that an American was among those killed and calling for an immediate end to the violence.

President Donald Trump, meanwhile, left open the possibility of U.S. involvement in Saudi Arabia's military campaign against the Houthis, saying, "We may.

We're gonna look at it.

We move very quickly." The escalation comes nearly three weeks after a senior Iranian official threatened to paralyze neighboring countries' airports if they cooperated with U.S. efforts to restrict Iranian flights.
