BUJUMBURA, Ramadan 11, 1436, June 28, 2015, SPA -- At least two people were killed overnight in the Burundian capital Bujumbura, relatives and friends said on Sunday, a day before parliamentary elections were due to be held amid an opposition boycott and fears of violence, Reuters reported. The opposition has said it would boycott Monday's vote and presidential elections on July 15. Dozens have been killed in the unrest and the U.N. refugee agency UNHCR says almost 127,000 people had fled to neighbouring states, many citing fears about election-related violence. In the night to Sunday, a police officer shot and killed a university student in Bujumbura's Jabe neighbourhood while he was returning home from visiting family, his brother said, giving his name only as Alexis for security reasons. A Reuters witness said loud explosions could be heard during the night in other parts of the city, accompanied by suspected gunfire. Also in Jabe, another man was killed in a suspected grenade attack, his friend said. --SPA 13:47 LOCAL TIME 10:47 GMT www.spa.gov.sa/w
