Another attack on UN personnel John Boonstra August 18, 2009That it occurred in Somalia, which has seen far too many deaths of UN workers, should come as no surprise. But this time, the UN fought back.Suspected Islamist insurgents stormed a United Nations compound overnight in southern Somalia, witnesses said on Monday, but UN guards fought back and killed three of the attackers in a gun battle.One UN official in Wajid, 70km northwest of Baidoa, said about 10 heavily armed men attacked them overnight. The compound is used for storing humanitarian aid."After several minutes shooting our security guards repulsed the attackers and killed three of them," the UN official told Reuters.While it was very fortunate that no UN personnel were killed (one guard was injured), it must be said that this success should not be taken as a policy blueprint. UN guards are not meant to defend against bands of militants, and it's only a matter of time until an incident like this goes much, much worse.
