Flash floods and landslides caused by heavy rain have killed five people in northeastern Turkey overnight, according to local media reports.

The casualties included three members of one family who died when their house was crushed by a landslide on Wednesday night near the border with Georgia, Anatolia news agency reported.

A five-story building in the town of Kale collapsed and several buildings and a mosque in Demiciler were heavily damaged, DPA reported.

The flash floods come only two weeks after more than 30 people were killed in flooding around Istanbul, when Turkey experienced its worst flooding in over 80 years.

The Governor of Artvin province Mustafa Yemlihalioglu said the number of casualties were not high because many areas had already been evacuated as rain began to pour.
