Workers are fixing a leak at a site where an oil well is being dug in northern Kuwait, state news agency Kuna reported on Wednesday.

The agency quoted Saad Al-Azemi, spokesman for the Kuwait Oil Company (KOC), as reporting that "no reading of any H2S (hydrogen sulphide) gas leak from the incident" had been recorded at the oil field.

He said specialised teams were dealing with the incident.

In a later statement, Al-Azemi said the spill had not affected KOC's operations and production processes in Kuwait, a major oil producer and Opec member.

Kuwaiti media published photos of a fire it said was burning at the scene. The Arabic-language Al-Rai news service said photos of a large fire were circulating on social media.  - Reuters
