A man convicted of involvement in a plot to blow up a Christmas market in Strasbourg in 2000 has been extradited from the UK to France, officials say.
The group's target was Strasbourg Christmas market
Algerian Rabah Kadri, who was convicted and sentenced to six years by a French court in December 2002, was flown into a military airport west of Paris.
Officials say he can serve out his term in France or appeal and face retrial.
One of 10 people to be sentenced over the plot, he had been held in Britain after being arrested in London in 2002.
He was arrested in November 2002 connection with a reported attempt to attack the London Underground and charged with possessing material that could be used to commit terror attacks.
He was charged again in February 2003 over an alleged plot to concoct a chemical weapon.
Kadri was one of 10 Algerians and French-Algerians convicted of taking part in the Strasbourg plot in December 2002. A further four had been convicted in Germany in 2003.
The group were known as the "Frankfurt group" because they were said to have hatched the plot in the German city.
The Strasbourg plot was to have used a timer connected to explosives to wreak havoc at the eastern French city's Christmas market, a picturesque stretch of decorated stands that attracts tens of thousands of shoppers each year.
