Interior Minister Suleyman Soylu said 12 people were killed by the floods in southeastern Sanliurfa province while two others died in nearby Adiyaman province, Habertürk writes.
Turkey's disaster management says more than a dozen professional divers were involved in rescue efforts in the provinces, the AP reports.
One of the victims, in the town of Tut in Adiyaman, was killed when gushing water swept a container house where a family of earthquake survivors lived, according to governor Numan Hatipoglu.
Several people have been evacuated from a drenched camp where earthquake survivors have taken shelter in tents. In addition, patients have had to be evacuated from a hospital, according to the AP.
