Several explosions were heard across Saudi Arabia’s capital Riyadh on Thursday, with diplomats reportedly taking shelter in their embassies and international schools also taking safety measures.

Tensions escalated in the Saudi capital on Thursday after blasts were heard and Yemen's Houthi's claims attacks. The explosions came hours after Yemen’s Houthi group claimed it had attacked King Khalid International Airport in Riyadh with a ballistic missile. The claim could not be independently verified.
Diplomats stationed in the Saudi capital had been instructed to shelter in their respective embassies, while residents said international schools had taken precautionary measures. At least one school moved children into a basement.
Two people working in Riyadh’s King Abdullah Financial District also said that some companies were evacuating staff, as reported by news agency AFP.
Explosions earlier this week
The latest developments came after several incidents in and around Riyadh earlier this week.
Loud explosions rattled Riyadh on Monday evening, followed by another explosion that echoed through northern parts of the city on Tuesday. The Houthis had claimed that they struck Riyadh airport and an Aramco refinery, although Saudi authorities had not publicly confirmed an attack on the airport.
King Khalid International Airport had also been facing frequent temporary airspace closures, according to flight-tracking website Flightradar24, while Saudi authorities had not publicly acknowledged closures or confirmed strikes on the airport.

Fighting escalates in Yemen
The developments in Riyadh come as fighting between the Houthis and Saudi-backed Yemeni government forces has intensified.
The conflict escalated in July after a four-year ceasefire, with Houthi forces making territorial gains along Yemen’s Red Sea coast.
Saudi-backed Yemeni government forces have since launched a counter-offensive to retake strategic territory around the Red Sea and the Bab el-Mandeb Strait, a key route for global shipping and energy supplies.
More than 200,000 people have been displaced since the latest fighting began in July, according to the International Organization for Migration.
The Houthis and Saudi-led coalition have made competing claims about military operations and attacks, which could not be independently verified.
In Riyadh, diplomats remained under instructions to shelter in their embassies and schools took precautionary measures as explosions were heard across the Saudi capital on Thursday.
