Burundi's government on Saturday rejected the African Union's plans to deploy a 5,000-strong peacekeeping force to stop escalating violence triggered by President Pierre Nkurunziza's extended tenure in office, a government spokesman said.

If the African Union sends troops without Burundi's consent it will be viewed as an attack, said government spokesman Philippe Nzobonariba. Burundi has enough forces to maintain peace, he said. Burundi has been in turmoil since April when Nkurunziza's candidacy for a third term was announced. Violence escalated following Nkurunziza's re-election in July.

Last week 87 people died when an unidentified group attacked three military installations. Burundi's security forces responded by going on a rampage in parts of the capital, Bujumbura, regarded as centers of opposition. Police and military are accused of dragging more than 150 civilians from their homes and shooting them at point blank range, according to human rights groups. Burundi's government insists its troops acted professionally.

In response to the violence, the African Union on Friday authorized sending a peacekeeping force to Burundi to stop the political violence. In another effort at mediation, Burundi's fighting sides are to meet on December 28 in Uganda to try to resolve the crisis, Uganda's defense minister said Saturday. However the chances for these negotiations are not certain as the Nkurunziza government refused to participate in previous talks.

At least 400 people have been killed since April 26, when it was announced Nkurunziza would run for a third term, according to human rights groups. Nearly 3,500 people have been arrested in the political crisis and 220,000 people have fled the country.
