Flash floods killed at least 13 people living in tents and container housing set up across Turkey's quake-hit region Wednesday, piling more pressure on President Recep Tayyip Erdogan ahead of crunch elections.

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, local media reports said.

More than 48,000 people died in Turkey and nearly 6,000 in Syria in the Feb. 6 disaster, the region's deadliest in modern times.

Hundreds of thousands of Turkish quake survivors have been moved into tents and container homes across the disaster region, which covers 11 provinces across Turkey's southeast.

Torrential rains hit the area late Tuesday and the weather service expects them to last until late Wednesday.

Turkish media said the floods killed 11 people in Sanliurfa, about 50 kilometers north of the Syrian border.

Two people also died in nearby Adiyaman, including a one-year-old, the reports said.

Images showed the waters sweeping away cars and flooding temporary housing set up for earthquake victims.

The Sanliurfa governor's office said the flooding also reached the ground floor of one of the region's main hospitals.
