I am a Yoruba, living in Ibadan. This issue of tension in Onitsha about Hausa/Yoruba shouldnt bring any cause of discussion that might fuel tribalism problems between all major tribals groups.
To start with, NIGERIA as a whole needs a good cleaning and sanitation. I am in supports of Fashola, Lagos state government. The Sanisation affected not only the Igbos/Yorubas/Efik/Calabar people. It affected everybody.
Same cleaning is going on in Ibadan city/Oyo State. The goverment has embacked on same way Lagos has done. Nonetheless, it has affected homes, shops and properties, the cleaning up has been seen as for widening of roads, and keeping up to 20-50m away from the roads.
I think Nigeria needs a general cleaning up especially in our market place areas. Visit Ibadan main area and see for yourself how disusting it is.

We YORUBAS ARE TOO TRIBALISTICS, always seeing shortcomings of others whenever we are affected in one way or the other by other group.
The market road ONITSHA in question is definitely not only HAUSA/YORUBA, there are other minority groups as well as the Ibos.
When FASHOLA cleaned up, all tribaes are affected, people say a lot of negative things but the job is done.We are happy to be proud YORUBAS with our megacity.
So please, Lagos is just a mirror for others to copy and it is high time we start rebuilding.
