Nigeria has been rocked by yet more attacks against the country’s sizeable Christian population. Africa’s most populous country - split nearly 50-50 between Christians (concentrated in the south) and Muslims (concentrated in the north, where Sharia law is widely implemented) - saw gunmen attack a Catholic Mass earlier this month, killing over fifty worshippers. That attack, at St Francis Catholic Church in Owo town, Ondo state in south-western Nigeria, was blamed by some officials on Fulani herdsmen while others pointed to the Islamic State West Africa Province.
