At least 11 people have died and six others were injured when an avalanche hit a group of climbers on Mount Mizhirgi in the Kabardino-Balkaria region of the North Caucasus on Sunday. The incident occurred around 5pm local time (2pm GMT), according to local emergency services. The group consisted of 33 climbers, and by 9am local time on Monday, ten had successfully descended the mountain. However, the fate of six climbers remained unknown, as search efforts continued. Emergency services deployed more than 50 workers to assist in the search and rescue operation. However, the efforts were complicated by the rugged terrain and the risk of additional avalanches, which made the situation even more dangerous. Mount Mizhirgi, where the avalanche took place, is one of the highest peaks in the region. Its western summit reaches 5,047 metres (16,558 feet), while the eastern summit is slightly lower at 4,927 metres (16,165 feet). It is classified as an ultra-high mountain, placing it among the 12 tallest peaks in the Caucasus region. The Caucasus is a well-known destination for climbers, attracting thousands of visitors each year. Nearby is Mount Elbrus, which is both the highest mountain in Russia and Europe, standing at 5,642 metres (18,510 feet). It is a popular climbing spot, with between 15,000 and 20,000 visitors annually. The region's challenging terrain and high-altitude peaks make it a favorite among experienced climbers, but also pose significant risks, as seen in this recent tragedy.
