There are approximately 2,000 Muslims in the country. The majority belong to the Sunni group, while a small number are Ahmadi. Non-traditional Christian churches and non-Christian religious groups are active throughout the country. The Papua New Guinea Council of Churches has stated that both Muslim and Confucian missionaries are highly active. Traditional religions are often animist. Some also tend to have elements of veneration of the dead, though generalisation is suspect given the extreme heterogeneity of Melanesian societies. Prevalent among traditional tribes is the belief in ''masalai'', or evil spirits, which are blamed for "poisoning" people, causing calamity and death, and the practice of ''puripuri'' (sorcery).
