At least 13 people have been killed and 66 injured after an explosion at Qatar's largest gas facility.

The city's main liquified natural gas (LNG) processing site suffered a "technical accident" in Ras Laffan industrial zone on Sunday night, the interior ministry said, with the city's skyline turning orange because of the explosion.

Qatar's Energy Minister Saad Sherida al-Kaabi said the explosion would not affect the country's exports, adding "this was an accident and not sabotage or hostile in nature".

The Ras Laffan Port is the largest artificial harbour in the world and has the world's largest LNG export facility. It was targeted by Iranian strikes earlier this year.

The blast on Sunday rattled windows and was felt across central Doha, panicking residents more than 70km (43 miles) from Ras Laffan.

Sherida al-Kaabi added the government was working on determining the cause of the blast which occurred at the Barzan local gas supply facility, he added there was no environmental risks.

However, the energy minister said it would be difficult to determine when operations would resume.

"Plant production was intentionally completely stopped since December 2025 due to urgent maintenance requirements, it was first restarted again only two days ago," Sherida al-Kaabi said.

An investigation has begun into the cause of the accident and Sherida al-Kaabi confirmed those killed from the blast were all from India and Pakistan.

The Embassy of India in Doha said it was in constant touch with the Qatari authorities and will render all help to the families of those who lost their lives or have been injured.

"We convey our deepest condolences to the families of those who have unfortunately passed away in the sad incident at Ras Laffan Industrial City last night," the embassy said in a post on X.

On Sunday, QatarEnergy, which is the country's state-owned energy company, confirmed the explosion occurred at "Barzan local gas supply facility in the evening hours of Sunday 21 June".

"Emergency response teams were deployed immediately to contain the fire, which is now under control."

The blast occurred as workers were restarting operations that were previously halted in March.

During the US-Israel war with Iran, the Ras Laffan Port suffered "extensive damage" from retaliatory strikes as Qatar is a major supplier of global energy.

Qatar had halted production in response to the conflict, pausing a fifth of the world's LNG. Shipments had begun to resume recently.
