Orcas Target Sailing Yachts in Aggressive Behavior Alarming Scientists

Two sailboats were attacked by orcas during an international race near Spain.
The orcas surrounded the boats, rammed into them, and bit their rudders for 15 minutes, causing damage.
No one was injured, but the encounters were described as "scary" and "dangerous" by the crews.
The behavior appears to be spreading and worsening, with over 20 incidents reported in May alone and cases of significant damage and boats sinking.
The reasons for the orcas' aggression remain a mystery, though some scientists hypothesize they are either playing or reacting to trauma.
