Off the coast of Colombia, as many as 2,000 sharks in a wildlife sanctuary have been massacred, says the Colombian government. A team of divers first alerted the government to the killings, according to the Guardian:
[The divers] saw a large number of fishing trawlers entering the zone illegally," [environmental minister Sandra] Bessudo said. The divers counted a total of 10 fishing boats, which all were flying the Costa Rican flag.
"When the divers dove, they started finding a large number of animals without their fins. They didn't see any alive," she said. One of the divers provided a video that shows the finless bodies of dead sharks on the ocean floor.
The obvious explanation is that the sharks were killed for their fins, which are often used to make shark-fin soup, a delicacy in East Asia.
