 Blast at Turkey's Tupras refinery kills four

An explosion in a storage tank at a Tupras refinery in the western Turkish province of Izmir killed four people but had no impact on production, the company said.

The blast occurred on Wednesday during maintenance work on a product tank at the Tupras oil refinery, killing four workers and injuring two others, Anadolu Agency reported.

The governor for the Aliaga district in Izmir province, Bayram Yilmaz, said that the blast occurred during work on a naphtha gas tank that had been out of use for a long time and confirmed that the explosion was an accident caused by gas pressure in a boiler.

Dogan private news agency reported that Yilmaz said there was no fire at the site and that production is continuing at the facility operated by Tupras.
