PARIS, France (CNN) -- Pirates attacked a French ship in the waters off Cameroon on Friday, taking 10 of the 15 crew members hostage, the French Foreign Ministry and the ship's owner said.
Six of those captured are French nationals, two are Cameroonians, one is Tunisian and one is Senegalese, said Bourbon, the shipping company. No one was injured, it said.
The ship and the staff still on board are now safe, Bourbon said, without providing details.
The attack happened overnight when armed men in three boats boarded the Bourbon Sagitta, a tug supply vessel, Bourbon said.
The Bourbon Sagitta had been assisting loading operations of crude oil from a field off the Bakasi Peninsula, about 180 kilometers (112 miles) from Cameroon's capital of Douala, the company said.
The pirates abducted the 10 crew members and fled.
French Foreign Minister Bernard Kouchner called for a crisis center to be activated in Paris to deal with the situation, the Foreign Ministry said.
The French consulate in Douala was in contact with the families of the hostages, the ministry said.
