Yaounde: Rampant search is underway in Cameron for vacationing of a French family held hostage.
A French family of seven members that include four children was on Tuesday kidnapped by armed gunman.
Military helicopters and all king of security is on a boost due to tensions created due to French role in operations in Western Africa.
Cameroonian President Paul Biya ordered tight security and a ministry statement said the Cameroonian government is in contact with Nigerian and French authorities.
Officials suggested the involvement of Boko Haram, one of Nigeria`s Islamic extremist sects.
The kidnapping came as thousands of French troops are deeply involved in a military intervention against Islamic extremists who had taken control of a big part of the West African country of Mali.
French President Francois Hollande, speaking at a Cabinet meeting Wednesday, called it an "odious act" and expressed particular horror that children were involved, according to his government spokeswoman.
France`s defense minister said Wednesday that there was no proven link between the French operation in Mali and the Cameroon kidnapping. But, speaking on France-2 television, Jean-Yves Le Drian said: "These are groups who adhere to the same fundamentalism and who have the same methods, whether it is in Mali, in Somalia or in Nigeria, who want to create a lawless zone" stretching from the Atlantic across the southern edge of the Sahara to Sudan.
France`s government warned French citizens to avoid travel in northern Cameroon after the kidnapping and urged anyone currently there to leave immediately.
French Foreign Ministry spokesman Philippe Lalliot, in an online exchange with reporters Wednesday, said that in northern Cameroon, "There was never a security incident linked to terrorism; Nigerian terrorist groups had never carried out actions in this part of Cameroon."
A Cameroonian government official said military helicopters were being used in the search.
The French gas group GDF Suez identified the captives as an employee working in the Cameroon capital of Yaounde and his family. French media says the children are between 5 and 12 years old.
Cameroon state television cited government sources in the locality saying that the three adults have been separated from the four children.
The family was on tour at the Waza National Park in Cameroon`s Far-North Region before they were abducted at gunpoint by five gunmen aboard motorbikes, according to paramilitary sources in the area.
