Aerial firefighting operations in Greece resumed on Monday morning, with five water-dropping aircraft and five helicopters deployed to support ground crews battling a major wildfire west of Athens.
The restart of air support comes a day after a midair collision between two firefighting planes resulted in two fatalities, temporarily halting aerial efforts in the region.
Authorities have arrested suspects believed to be responsible for starting the blaze, which officials say was sparked by a faulty power line.
The arrests mark a significant development in the investigation, potentially closing a chapter on the cause of the fire that has consumed significant resources across Southern Europe.
The incident adds to a growing toll from the wildfire crisis in Greece, where three firefighters previously died while battling blazes on the island of Crete.
Strong winds have continued to complicate containment efforts, hampering both aerial and ground operations and intensifying the risk to communities and infrastructure.
