Abuja- Nigeria was awaiting the arrival Friday of German President Horst Koehler and his wife Eva Luise for the start of a six-day visit devoted to bilateral and African issues.

In Abuja, Koehler will be meeting with Nigerian President Umaru Musa Yar'Adua and taking part, through Sunday, in the fourth "Africa Forum" for a review of a number of policy issues.

Abuja is the fourth venue for the Africa Forum, after meetings in Bonn, Ghana, and the German town of Kloster Eberbach.

Casting a shadow over the discussions in Abuja is the conflict in eastern Congo, amid fighting between government and rebel forces and the flight of thousands of refugees. (dpa)
