Paris: President Nicolas Sarkozy welcomed back the crew of a French yacht held hostage for a week by Somali pirates, as Paris prosecutors open an inquiry into the affair.

Le Ponant's 30 crew - 22 French, six Filipinos, a Cameroonian and a Ukrainian - were freed on Friday following negotiations that ended the standoff peacefully.

The former hostages were transferred in French helicopters to Djibouti, where France has its largest overseas military base, an AFP correspondent reported.

They were briefly greeted by Djiboutian officials and Dominique Decherf, the French ambassador to Djibouti, before boarding a plane that touched down in Paris Orly airport at 7:35 pm (local time).

Sarkozy, Defence Minister Herve Morin and Army chief of staff General Jean-Louis Georgelin were among the dignitaries waiting at the foot of the steps leading off the Airbus A 310 to welcome them.

The group broke off for emotional reunions with friends and families before walking the red carpet to join Sarkozy in the airport's VIP area to general applause.

"We were completely cut off from the rest of the world," the yacht s captain, Patrick Marchesseau, told waiting reporters.

"We didn't know that our families had been received at the Elysee (Palace, the president's official residence)."

Having thanked all those who had worked to free them, Marchesseau made an appeal on behalf of Ingrid Betancourt, the Franco-Colombian politician held by Marxist guerrillas in Colombia since 2002.

He said all the crew had thought about Betancourt during their time as hostages. But their captors had offered them no violence, either physical or verbal, he added.
