A flash flood at a campsite in northwestern Turkey near the border with Bulgaria killed at least four people and carried away bungalow homes. Two of the victims were found on Wednesday.
Rescuers were still searching for two other people reported missing at the campsite.
Another two people died in Istanbul, Turkey’s largest city, where Tuesday’s storms inundated hundreds of homes and workplaces in several neighbourhoods.
The victims in Istanbul included a 32-year-old Guinean citizen who was trapped inside his basement apartment in the low-income Kucukcekmece district, Turkish broadcaster HaberTurk TV reported.
The other was a 57-year-old woman who died after being swept away by the floods in another neighbourhood, the private DHA news agency reported.
Surging floodwaters affected more than 1,750 homes and businesses in the city, according to the Istanbul governor’s office.
They included a line of shops in the Ikitelli district, where the deluge dragged parked vehicles and mud into furniture stores, destroying the merchandise, DHA reported.
The floods also engulfed a parking area for containers and trucks on the city’s outskirts where people found safety by climbing on the roof of a restaurant, Turkish media reports said.

“It’s a disaster. … The steep terrain [along the coast] creates an enormous danger,” Prime Minister Nikolay Denkov said, adding “long-term solutions” would be needed to secure the area.
The rains were the heaviest since 1994 with as much rain falling in 24 hours as is usually seen in several months, according to head of the fire department, Alexandar Dzhartov.
Flooding, which had been rare on the Black Sea coast, is becoming increasingly common in Bulgaria with the impact of climate change and the poor maintenance of infrastructure.
