Italian firefighters are battling a wildfire that has been burning on the slopes of Mount Vesuvius since Friday, forcing authorities to close every hiking trail in the popular national park near Naples. The national fire service said on Sunday it has deployed 12 ground teams and six Canadair aircraft, with reinforcements arriving from other regions and drones used to track the fire’s spread. Park officials suspended all visitor activities “until further notice” to protect tourists and ease firefighting operations. The nearby Pompeii archaeological site remains open, although smoke from the blaze is visible from the ruins. Nearly 620,000 people visited Vesuvius’s crater last year, underscoring the potential economic impact of the closure. No injuries or damage to inhabited areas have been reported, and investigators have yet to determine the cause of the fire. Italy, like other parts of Europe, has faced increasingly severe wildfires amid hotter, drier summers linked to climate change.
