21 Dolphins Die After Attack By Rival Gang

Twenty-one dolphins that were apparently attacked by another species of dolphin have died after washing up on a beach in northern Mexico, authorities said.

Environmental activists launched a frantic operation to try to save the dolphins after a group of 54 washed up on a rocky beach in Bahia de la Paz, in Mexico's Baja California peninsula.

They managed to get 33 of the short-beaked common dolphins back in the water alive, but the rest died on the beach, the Mexican environmental protection authority, Profepa, said in a statement.
