Flash floods killed at least 10 people living in tents and containers set up across Türkiye's quake-hit southeast on Wednesday, according to media reports.
Several more people were swept away by the rushing water, which turned streets into muddy rivers in areas hit by last month's 7.8-magnitude quake.
Floodwater carried away cars and debris and inundated the basement and ground floors of some buildings, turning roads into rivers in central Sanliurfa, footage from social media and local broadcasters showed.
Search and rescue efforts for the missing and people trapped in their buildings continued with divers and boats, the country's disaster management authority (AFAD) said.
It said that more than 100 millimetres per square metre of rain had fallen in the affected provinces in the last 24 hours.
The provinces, home to some 2.7 million people, were hit by last month's earthquakes which killed more than 48,000 people in Türkiye and left millions homeless.
Thousands of people were staying in tents and container houses, some of which were flooded due to severe rain, after their homes were damaged by the earthquakes.
A container, which housed three earthquake victims, drifted away with the floods and a search was continuing for them in Adiyaman, the province's governor told broadcaster CNN Turk.
