SAINT-MALO, FRANCE (AFP) - Germany's Marcel Kittel of Argos dominated a group sprint to win the 10th stage of the Tour de France, held over 197km between Saint Gildas des Bois and Saint Malo on Tuesday.

Yellow jersey holder Chris Froome of Team Sky finished just behind the sprinters to retain his 1min 25sec lead on Spaniard Alejandro Valverde of Movistar.

Kittel, who was the winner of stage one of this year's Tour, pipped compatriot Andre Greipel (Lotto) to become the first sprinter on this year's 100th edition to win two stages.
