If you are interested in Nigerian news then you might want to view websites of different Nigerian newspapers so you can get different types of news that you may find interesting. Not all websites that belong to Nigerian newspapers would be featuring the exact same type of news from Nigeria, instead, they would all be featuring whatever they may have access to unless its some popular news that you may be after.
It would therefore be a good idea to get a list of websites that feature nigerian news, whether or not they may be owned by nigerian newspapers. This would make it possible for you to gain access to all items of news that may have been featured as you will be referring to different websites and consolidating news items that you could possibly get access to.
One of the easiest ways to simplify this process will be by checking out websites of news aggregators such as Google and Yahoo as they have summaries of different news from nigeria that have been published by different websites which would allow you to get started from somewhere and go by whatever attracts your interest the most. The best thing about it is that these sorts of websites can be searched using keywords so you get relevant news on specific themes that you may want to learn more about.
