Over 2,500 seals found dead on Russian coastline

Officials announced on Sunday that over 2,500 dead seals had been discovered along the southern Russian shore of the Caspian Sea.

The number of dead seals discovered on the coast was initially estimated by regional authorities on Saturday to be 700, but the Russian Ministry of Natural Resources and Environment later increased it to roughly 2,500.

Authorities in the Russian province of Dagestan stated that although the reason of the mass deaths was unknown, natural causes were most likely to blame.
