Saudi Arabia will not agree to a truce or a ceasefire with the Houthis until the Yemeni government that it backs regains all the territory it has lost in recent weeks, a regional source told AFP on Friday.

Saudi Arabia will also not bow to the Houthis' "military blackmail", the source added, speaking on condition of anonymity due to the sensitivity of the matter.

Three Saudi citizens, including a pilot, were killed and several other people were wounded in two attacks Thursday targeting King Khalid International Airport in Riyadh and a Saudia Airlines aircraft, Saudi Arabia's General Authority of Civil Aviation said Friday.

It marked the deadliest attack in the country since Saudi Arabia and allied forces in neighboring Yemen launched a major military offensive last weekend against the Iran-backed Houthi rebels in that country.

President Donald Trump said Thursday that he will not order a resumption of military strikes on Iran before the Nov. 3 midterm elections in the United States.

Trump, while stumping for Republicans this week, has hinted that he was confident that an endgame to the war could come in the days before or after the election, while also hinting that he remained open to resuming full-scale military operations against Iran.

Yemen's Houthis on Thursday called on staff at oil facilities in Saudi Arabia to leave to avoid being targeted as hostilities escalate with Riyadh, which backs Yemen's internationally recognized government fighting the Iran-backed group.

"Employees at all oil facilities must leave areas that are targets for our forces, so as not to endanger their lives," Houthi military spokesman Yahya Saree wrote on X, while also issuing a warning "to airlines, airports, travelers and their staff".

Nine Syrian sailors are missing following a drone strike that sank a commercial ship off the coast of Bulgaria, a Syrian official told AFP on Thursday, after rescuers called off search operations.

Bulgarian authorities said no survivors had been found from the ship, after drones hit two commercial vessels early Tuesday in the Black Sea, the latest fallout from the Ukraine-Russia war in recent months.

Turkey's foreign minister on Thursday ruled out sending troops to confront Yemen's Houthi forces, despite a defense pact with Saudi Arabia.

"This is a defense agreement," said Hakan Fidan. "This is not an offensive agreement. That is, Turkey will not send its troops to another country's territory to launch an attack."

Prime Minister Benjamin Netanyahu’s former military secretary has accused the Israeli leader of altering official transcripts of phone calls from the morning of the Oct. 7, 2023, Hamas-led attacks.

The accusations by Maj. Gen. Avi Gil came in a wide-ranging interview with the right-wing Israel Hayom newspaper.

Several explosions were heard in Saudi Arabia's capital of Riyadh on Thursday, including a large blast at the city's international airport, a witness told The Associated Press, a day after the kingdom said an attack there killed one person and wounded others.

The cause of the blasts was not immediately known. There was no immediate claim of responsibility. Iran-backed Houthi rebels in neighboring Yemen have repeatedly claimed attacks against airports, military and oil facilities in Saudi Arabia in recent days.

Israel said the British consulate in Jerusalem ended its functions on Thursday but that seven diplomats would be allowed to remain in a limited capacity, with the UK saying it would continue to offer "vital services".

The move comes after Israel ordered the closure of the consulate in September as retaliation after London led Western sanctions over violence by Israeli settlers against Palestinians in the occupied West Bank.

A Palestinian man was killed and nine people were injured during an Israeli settler attack followed by army intervention in an occupied West Bank village on Wednesday, according to the mayor and the Palestinian health ministry.
