Obasanjo arrived in Senegal on Tuesday to try to mediate a solution to the country's political impasse, less than a week before a contentious presidential election takes place. In the hour before his arrival, police once again fired tear gas to disperse demonstrators as they took to the streets and set fire to tires in a show of anger over the candidacy of the country's 85-year-old leader Abdoulaye Wade.(AP Photo/Tanya Bindra)
