BUJUMBURA JULY 21, 2015(CISA)- Burundi began voting in its disputed presidential election on Tuesday with a low turnout in several polling stations after widespread tension over President Pierre Nkurunziza’s decision to stand for a third consecutive term. Polls opened at 06:00 local time (04:00 GMT) after a night of gunfire and explosions killed a police officer and a civilian in Bujumbura, BBC News reported July 21. The president’s critics say the vote is unconstitutional, as the president is entitled to stand for two terms only. The president’s office has described the latest protests as terrorist acts intended to disrupt the election. The African Union (AU) has not sent observers – the first time it has taken such a stance against a member state.
