2 French soldiers likely killed in failed hostage rescue, defense minister says January 14, 2013 -- Updated 1449 GMT (2249 HKT) An undated TV grab shows Denis Allex, a French hostage allegedly held -- and possibly killed -- by Somali militants. French officials say it is likely two soldiers died and a hostage was killed in a raid in Somalia Militants say the hostage is still alive and being held at an undisclosed location (CNN) -- A soldier missing in action since a failed attempt to rescue a French hostage in Somalia is most likely dead, France's defense minister said Monday. The hostage, Denis Allex, also apparently was killed, Defense Minister Jean-Yves le Drian said. French officials had previously confirmed that one soldier died in Friday's failed attempt to rescue Allex from Islamist militants. On Monday, le Drian said it was likely that a total of two French soldiers were killed. "Everything points to the fact that the hostage was murdered and that the missing soldier has been killed," le Drian told CNN affiliate BFM. Al-Shabaab, the al Qaeda-affiliated Islamist movement that has been holding Allex, said Monday that the hostage remained alive in an undisclosed location. The militants also said Monday that a French soldier who had been injured in the attempted rescue had died of his wounds. A Twitter post from Al-Shabaab on Monday showed a purported photograph of that soldier with a message to France's president: "Was it worth it?" On Friday, French forces engaged in a fierce gunbattle with militants in their attempt to rescue Allex, who was a member of the DGSE, France's equivalent of the CIA and a part of its Defense Ministry. The clashes in Bulo Marer, about 75 miles (120 kilometers) northwest of Mogadishu, the capital, ended with 17 Islamist fighters dead, according to the French Defense Ministry. On Monday, le Drian said the failure of the rescue mission was "extremely regrettable." "The operation almost succeeded," he told BFM. They are very complicated and risky missions, because we are behind enemy lines. CNN's Nima Elbagir, Dheepthi Namasivayam and Richard A.
