People sing in the streets in Ziguinchor, an opposition stronghold, as results come in from Senegal's presidential elections. Opposition figure Bassirou Diomaye Faye appeared clearly ahead of the governing coalition's former prime minister, Amadou Ba, according to provisional results published by local media and on social networks. However, the governing coalition backing presidential candidate Amadou Ba said late Sunday said it was "certain" the election would go to a second-round vote. IMAGES
