A fire at a perfume warehouse in north-western Turkey has killed six people.

The blaze broke out at 09:05 local time on Saturday in Dilovasi, Kocaeli Province's governorship said.

The province's governor Ilhami Aktas told Turkish outlet CNN Turk that five people are in the hospital, with one in critical condition receiving treatment at a burns unit.

The fire has since been extinguished.

Images shown by Turkish media reveal firefighters battling large flames.

I heard an explosion... I looked from my balcony and saw that the clothes of a colleague had caught fire. I took a hose and I put the flames out. I then saw flames engulf the factories. There were cries from the building, recounted a witness to local TV.

The origins of the fire in the Mimar Sinon neighborhood remain unclear, prompting Justice Minister Yilmaz Tunc to announce a judicial investigation while the labor ministry also began its inquiry.

Situated around 70 kilometers (43 miles) from Istanbul, Dilovasi is an industrial town with numerous depots and factories.
