Story Link Police in Papua New Guinea have arrested 320 people for practicing sorcery and religious cults, the National newspaper reported Thursday. Belief in sorcery is widespread in this jungle-clad, mountainous South Pacific island nation where some villages only encountered Western civilization in the 1930s. Police raided three villages Monday near the city of Lae on the north coast and arrested leaders of a "cargo cult" and their followers, the newspaper said. Those arrested were aged between 20 and 70. Cargo cults believe that Western goods or cargo, first encountered through missionaries and explorers, are created by ancestral spirits. They have been known to build airstrips in the jungles in the belief that planes would land with cargo. One group led by two women used menstrual blood as "sacred water" to enable them to see "invisible things," said the newspaper in the capital, Port Moresby.
