Turkish authorities have raided a workshop in the Aegean coastal city of Izmir and seized more than 1,200 defective life-jackets that would have been sold to migrants, a newspaper report says.

The newspaper Hurriyet said Wednesday the raid on the workshop came at the same time as the bodies of dozens of people who drowned in two separate boat accidents washed up on Turkey's Aegean coast Tuesday.

Hurriyet said the life-jackets were made of material that doesn't float but becomes heavy when soaked and causes the wearer to sink.

At least two of the employees at the workshop were Syrian girls, the newspaper reported.

The International Organization for Migration says 3,771 people drowned trying to reach Europe last year.
