Where is the source of Niger River Which direction does it flow and where its delta?

The Niger River originates in the Fouta Djallon highlands of Guinea. It flows northeasterly through Mali, where it is joined by the Bani River, and then turns southeastward, forming the border between Niger and Benin. The river then flows through Nigeria, where it is joined by the Benue River, and finally empties into the Gulf of Guinea.

The Niger River's delta is located in southern Nigeria. It is a complex network of channels and distributaries that cover an area of over 20,000 square kilometers. The delta is home to a rich diversity of plants and animals, and is an important source of food and water for the people of the region.
