A volcano in Russia's far eastern region of Kamchatka has begun erupting, spewing ash up to 6 kilometers into the air, the regional branch of the Emergency Situations Ministry said Monday.
The nearly 5,000-meter-high Klyuchevsky volcano has been assigned a "yellow" threat level for aviation safety, which means its eruption does not pose a threat to planes flying over the area, the ministry said in an online statement.
Travel agencies have been advised against conducting tours in the vicinity of the volcano, and residents of nearby areas have been urged to keep their doors and windows closed and avoid going outside.
So far, none of the volcanic ash has wound up in residential areas, the ministry said.
The volcano began erupting on Sunday. It is not clear when the eruption is expected to end.
