Burundian President Pierre Nkurunziza said he may seek a fourth term, if the East African country's citizens should want him to run for office in 2020, dpa reported. "If [Burundian citizens] request me to run again for the presidency in 2020, I will not betray their will," Nkurunziza said Friday on local radio stations. The national constitution would have to be amended by a parliamentary vote with three-quarters majority or national referendum in order for Nkurunziza to run again. At his inauguration in August 2015, he had promised that he would not run for president in 2020. "The promise was made in a specific context that can change in case citizens make the request," said Nkurunziza. Burundi has been in turmoil since last year, when Nkurunziza announced his bid for a third term in office, despite a constitutional two-term limit. He won an election to a third term in 2015. A commission created by Nkurunziza came to the conclusion that the people wanted to put an end to term limits in the country. But critics say the survey was inaccurate because the population was afraid to answer questions honestly. The East African country's 10-million-strong population has seen a string of ethnic massacres, including the 1993-2005 civil war, which left 300,000 people dead.
