Two flesh-eating piranha fish have been caught in a river separating Turkey from Greece, Greek television channels have reported.
A Turkish fisherman caught a 18-inch piranha in the Evros River on July 31, reports said on Wednesday.
Earlier this week, a Greek fisherman caught a 9-inch piranha on a fishing rod, using sweet corn as bait.
Piranhas, known for their sharp teeth, voracious appetites, and occasional cannibalism, inhabit South American rivers. It is not clear how the fish got into the Evros.
The river has been a major entry point for illegal immigrants from Asia into Europe. Last year, more than 55,000 people crossed the river to get into Greece, a 17-percent rise from the year before, according to Frontex, the European Union's border protection agency.
Earlier this year, Greek authorities started to build a 12-kilometer (7.5-mile) fence along the border to prevent illegal immigration, a move criticized by human rights groups.
