This is one smart African country. At least the leaders are proactive. Back in 2002 Boko Haram started making havoc in Nigeria, and spread to other North African countries with the resulting persecution, killings and starvation of Christians.
Angola understood what has to be done, long before the threat entered their country. They closed down and destroyed mosques, they refused to register any Islamic religion, and they never once said they dont want Islam. It was always about, building permits, no approval for that structure, and tied them up in paperwork. Anyway, read it yourself

Europeans should take note, instead of playing with fire.
