Burundi's ruling party chose President Pierre Nkurunziza to run for a third five-year term on Saturday, a move critics say is unconstitutional and may trigger unrest in the East African country.
Opposition groups promised protests if Nkurunziza runs, saying it would undermine a peace deal that has kept the country calm for a decade since an ethnically-fueled civil war ended in 2005.
Any flare-up in Burundi threatens broader repercussions. It could draw in neighboring Rwanda, where 800,000 mainly Tutsis and moderate Hutus were killed in a 1994 genocide, and create turmoil in a region where other presidents, including Joseph Kabila in Democratic Republic of Congo, are nearing the end of their constitutionally defined term limits.
Burundi's Constitution says the president is elected for a five-year term, renewable only once. But Nkurunziza's supporters say his first term should not count because he was chosen by parliament rather than having been voted into office.
