Houthis threaten Saudi Aramco facilities and airports
The blasts in Sana'a were reported shortly after the Saudi-led coalition ordered an evacuation as the Houthis responded "toughly".
Yemen's Houthis have warned all employees and civilians near Saudi Arabia's oil facilities to evacuate oil sites, calling these sites "legitimate targets".
The group's spokesman, Yahya Saree, issued an evacuation warning on Tuesday following a Saudi-led coalition statement asking civilians to evacuate Yemen Oil Company's Al-Sabah central station in the Houthi-controlled capital Sanaa ahead of a planned military operation.

End of list Shortly after the Saudi-led coalition was ordered to evacuate, Al Jazeera's team on the ground reported hearing an explosion in Sana'a. Houthi-affiliated media say that airstrikes by Saudi-backed forces attacked oil facilities in the Sabah area of the capital.
Following the reported explosions, Saari said Houthi fighters were fighting Saudi-backed forces in Sanaa.
Saree reacted to the coalition's evacuation order and warned that any attack on Sana'a would be met with a "hard and painful" response in Riyadh, the capital of Saudi Arabia.
Saree said in a statement on X that the Houthis will target the places they were ordered to evacuate if the coalition led by Saudi Arabia takes action. The attack on Sana'a
Civilians were told to evacuate Aramco headquarters in Dammam, King Khalid International Airport and an Aramco-affiliated refinery in Riyadh.
Saturday's attack on King Khalid International Airport left at least 13 dead and more than 300 injured, shaking the world's largest crude oil exporter. On Sunday, one more person was killed and 11 people were injured after a bullet hit Riyadh airport.
Many international airlines, including Air France-KLM, Air India, Etihad, Lufthansa, Delta, Gulf Air and Qatar Airways, have suspended flights to Saudi Arabia and neighboring countries following the deadly weekend Houthi attacks.
The kingdom, which backs Yemen's internationally recognized government, was still dealing with fresh attacks on Tuesday, and the coalition said its forces intercepted three drones north of Riyadh.
Saree also reiterated the Houthis' warning to Saudi Arabia's airports following recent attacks on airports and oil facilities across the country since last week, fueled by the wider regional conflict between the US and Iran.
Saudi Arabia has launched attacks against the Houthis in recent weeks and is backing a Yemeni government counteroffensive known as the "Yemen Dawn" after seizing a strategic area along the Red Sea coast last month.
