The French Navy Frigate Nivose responded to a distress call from a Liberian-flagged ship under pirate attack in the Indian Ocean, and foiled the attack.
They then pursued and captured the pirate mothership with 11 pirates and 2 skiffs rigged for piracy.
Good on you, Marine Nationale.
The capture happened about 900 km (~400 nm) off Mombasa, Kenya, out in the Indian Ocean.
For those of you lacking a map reference: The major islands of the Seychelles are roughly 1500 km due east of Mombasa.
