It began with an incident just off the coast of Gibraltar, but it quickly spread.

Boats sailing in the area were suddenly coming under attack.

It's the sound of a pod of orcas or killer whales bashing a boat until it rocks violently

and tearing at its rudder.

It's one of hundreds of incidents since 2020, which began around Gibraltar, that spread

The pod rammed the boat continuously for over an hour, managing to remove the rudder.

I start taking my nap and 30 minutes later, boom, I got really scared.

Scores of boats damaged, three of them sunk to the ocean floor.

And last month, they spread to the UK when a yacht was rammed by a killer whale off the coast of Scotland.

After thousands of years of living peacefully alongside humans, it's left experts searching

You're listening to stories of our times from the times and the Sunday times.

I thought it was going to be an Orca-shaped sock.

It was so exciting.
