French miscalculated rebel firepower in Somali raid

French troops underestimated the strength of Islamist rebels when they launched a failed bid to free an intelligence officer held hostage in Somalia, the French defense minister said. One French soldier died and another went missing during the raid in which the hostage was probably killed by his captors, Defence Minister Jean-Yves Le Drian said Saturday. Seventeen guerrillas were killed, he added. The overnight operation involving some 50 troops and at least five helicopters to free the intelligence agent, with the alias of Denis Allex, was launched by elite forces from the DGSE secret service, he said. "The resistance was stronger than expected and the heavy weaponry at the hands of the terrorists were clearly underestimated," said Le Drian. He said that one commado was dead and another missing and that "all indications" point to that fact Allex had been killed by his captors belonging to the Shebab, a Somali Islamist group affiliated to Al Qaeda. However the group denied that Allex was dead and said they were also holding the missing French commando. They also threatened reprisals against France. "In the end, it will be the French citizens who will inevitably taste the bitter consequences of their government's devil-may-care attitude towards hostages," a Shebab statement said. French President Francois Hollande said the operation failed "despite the sacrifice of two of our soldiers and without doubt the killing of our hostage", but underscored France's determination "not give in to the blackmail of terrorists." Le Drian said the raid in Bulomarer, some 110 kilometres (70 miles) south of Mogadishu, was sparked by the "intransigence of the terrorists who have refused to negotiate for three and a half years and were holding Denis Allex in inhuman conditions." Although the raid happened on Friday, the same day French troops launched air strikes on Islamist militants in Mali, in west Africa, the minister said the operations were not connected. Allex is among nine French hostages in Africa of whom at least six are held by Al-Qaeda in the Islamic Maghreb (AQIM). A French expert involved in several hostage negotiations said "talks with the Somali Islamists had become impossible due to the huge ransom demanded and the marked opposition of the Americans to the payment of ransom. "Denis Allex became a human shield and an operation had become indispensable," the expert said, speaking on condition of anonymity. A source close to the case, also speaking on condition of anonymity said the DGSE had been preparing a raid to free Allex for more than a year. It had "been cancelled at the last minute three or four times as we did not have a solid confirmation of his location," the source added. The Shebab statement said the French had carried away "several" of their dead. "The helicopters attacked a house... upon the assumption that Denis Allex was being held at that location, but owing to a fatal intelligence blunder, the rescue mission turned disastrously wrong. "The injured French soldier is now in the custody of the mujahedeen and Allex still remains safe and far from the location of the battle," it said. A Bulomarer resident, Idris Youssouf, told AFP: "We don't know exactly what happened because the attack took place at night, but this morning we saw several corpses including that of a white man. "Three civilians were also killed in the gunfight," he said. Allex was kidnapped in Somalia on July 14, 2009 -- Bastille Day -- along with a colleague. A second hostage, named as Marc Aubriere, was free a month later, in what the French government said was an escape. The Al-Qaeda linked Shebab lost their main strongholds in the south and centre of Somalia following an offensive launched in mid-2011 by an African Union force, but they still control some rural areas. Allex appeared in a video in June 2010 appealing to Paris to drop its support for the Somali government. He last appeared in another video in October looking gaunt and calling on Hollande to work for his release. Somalia has not had an effective central government since 1991. France has a recent history of botched operations, including a failed joint raid with Niger forces in 2011 that left both hostages dead: and another in Mali that led to the hostage's execution. In 2009, French commandos launched a raid to free a French family whose yacht had been hijacked by Somali pirates. They retook the boat but accidentally shot the father.
