A black bear roaming the runway at Yamagata Airport in northern Japan led to flight cancellations and the closure of the airport to passengers. The bear, approximately four feet tall, was first seen near the runway in the morning, causing delays for four flights. Despite attempts to chase it away, the bear reappeared later in the day, prompting the closure of the runway again. With hunters setting up traps and police officers surrounding the airport, officials declared a stalemate. Due to the ongoing bear presence, the airport planned to keep the runway closed until the evening. The incident highlights the increasing human encounters with bears in Japan, with efforts being made to protect both people and infrastructure from these animals. (Cbsnews)
