It is illegal in Kenya to own any type of firearm without a valid gun ownership license as spelled out under the Firearms Act (Cap. 114) Laws of Kenya. Anyone who is 12 years or older can apply to privately own a gun. However, such persons must provide in writing to the Chief Licensing Officer (CLO) stating genuine reason(s) for their need to privately own and carry a firearm. It remains at the discretion of the CLO to make a decision to award, deny or revoke a gun ownership license based on the reason(s) given. Anyone seeking to hold a gun license must pass the most stringent of background checks that probes into their past and present criminal, mental health and well as domestic violence records. Failure to pass one of these checks automatically bars one from being permitted to own a firearm. These checks are regularly repeated and must be continually passed for anyone to continue holding the gun license. Failure to pass any of these checks at any stage, means an automatic and immediate revocation of the issued license. Once licensed to own a gun, no permit is required in order to carry around a concealed firearm. -- Wikipedia.
'All Muslims leave... we only want to kill non-Muslims': Gunmen massacre at least 25 in Kenyan shopping mall after releasing anyone who could prove they were Islamic by reciting a prayer.
LATER: I just saw a CNN report on this and while they mentioned "terrorists" and "armed gunmen" (is there such a thing as an unarmed gunman?) they failed to make any reference to the motive or the fact that they were Muslims.
