DAKAR, Senegal (AP) -- Former Nigerian President Olusegun Obasanjo has arrived in Senegal to mediate the country's political standoff, while police once again fired tear gas to disperse protesters in the capital.
Demonstrators are calling for the departure of 85-year-old President Abdoulaye Wade, who has defied calls to step down and is instead running for a third term in this weekend's election.
Obasanjo says that his message is as follows: "This country is very beautiful, and nothing should be done to destroy it."
The retired Nigerian leader has helped mediate disputes in other parts of Africa, including last year when he traveled to Senegal's neighbor Ivory Coast to urge its president to step down after losing the presidential election.
