NAIROBI, Safar 04, 1437, November 16, 2015, SPA -- At least four people died in shootings and explosions in various neighbourhoods in Burundi's capital on Sunday, while the government-supporting mayor's house was attacked during a night of violence, witnesses and local administration said, according to Reuters. Last week, the United Nations Security Council asked Secretary-General Ban Ki-moon to report within 15 days on options for boosting the U.N. presence in Burundi amid growing concern that the violence could spiral into an ethnic conflict. Memories are still raw in the region of the 1994 genocide in neighbouring Rwanda. Attackers targeted a police post in the south of the capital, killing one police officer and injuring another, said a police officer who witnessed the incident and did not wish to be named. Shootings started at around 9.00 p.m. local time in areas like Mutakura, where three people were wounded. The gunfire intensified at midnight and was heard across Bujumbura for several hours, another police officer who did not wish to be named said. --SPA 13:52 LOCAL TIME 10:52 GMT www.spa.gov.sa/w
