4 people were reported dead and more than 100 injured as thousands of firefighters battled huge blazes spreading across the Mediterranean resort regions of Turkey’s southern coast.

Officials also launched an investigation into suspicions the fires that broke out Wednesday in four locations to the east of the tourist hotspot Antalya were the result of arson.

Turkey’s disaster and emergencies office said three people were killed - including an 82-year-old who lived alone - and 122 injured by the fires.

The fires first emerged across a sparsely populated region about 75 km east of Antalya.
