MOSCOW, Russia (AP) — About 2,500 seals have been found dead on the Caspian Sea coast in southern Russia, officials said Sunday.
Authorities in the Russian province of Dagestan said it was unclear why the mass die-off happened but that it was likely due to natural causes.
Regional officials initially reported Saturday that 700 dead seals were found on the coast, but the Dagestan division of the Russian Ministry of Natural Resources and Environment later raised the figure to about 2,500.
Zaur Gapizov, head of the Caspian Environmental Protection Center, said in a statement that the seals likely died a couple of weeks ago. He added that there was no sign that they were killed or caught in fishing nets.
