A man died after being attacked by two bears near a residential house on the outskirts of the Far Eastern port of Vilyuchinsk, police said on Monday.
The man was walking some 400 meters away from the house when he was attacked.
Police tracked down the bears and killed them.
Meanwhile, local residents said they had seen a bear with a cub on the outskirts of the city. The area has been patrolled around the clock to prevent more attacks.
This spring bears in the region woke up from their winter hibernation earlier than usual, and a lack of food resources is likely to prompt the animals to move closer to residential areas.
The Kamchatka brown bear, also known as the Far Eastern brown bear, is one of the largest in the world, with its body length reaching 3 meters and its weight 700 kilograms. The Far Eastern Kamchatka Peninsula is home to more than 18,000 brown bears.
Several bear attacks on people are registered in the region every year.
