LAGOS (Reuters) - Nigeria’s former President Olusegun Obasanjo has gone to Ethiopia, his spokesman said on Monday, as various African and European nations pushed for a mediated solution to a nearly two-week conflict in the Tigray region. “The former president is on his way to Ethiopia right now, but I don’t know what he is going to do there,” spokesman Kenny Akinyemi said. A diplomat in Addis Ababa confirmed his arrival.
