Floods in Russia's Far East had forced the evacuation of more than 2,500 people by Monday, the ministry of emergency situations said, after Russia joined the list of countries battered by rainstorms in the wake of Typhoon Khanun.

After lashing southern Japan last week, Khanun weakened into a tropical depression as it swept across the Korean peninsula to make landfall in northeast China on Friday night, causing mudslides in Liaoning Province that killed at least 21 people.

In the Russian Far East, 28 settlements were cut off by Monday. Large stretches of roads and 4,620 houses were flooded in 15 municipalities, the ministry said on the Telegram channel.

The ministry said floodwaters had begun to recede in most parts of Primorye region, and the worst flooding was on the Malinovka river near the village of Rakitnoye. The Pacific coast port of Vladivostok is the administrative center of Primorye region.
