Overnight blasts, gunfire mar Burundi presidential vote

Blasts and gunfire overnight marred Burundi's presidential election on Tuesday, which the opposition said it would boycott after President Pierre Nkurunziza sparked a crisis by seeking a third term in office.

The rebel-turned-president's campaign for another five years in power led to weeks of protests, a failed coup attempt and clashes between rebel soldiers and the army, stoking tensions in a region with a history of ethnic bloodshed.
