Burundian President Pierre Nkurunziza said Wednesday he would fight proposed African Union peacekeepers if they set foot on Burundian soil, defying intense global pressure to accept the force.
"Everybody should respect the borders of Burundi. If the troops are in violation of this decision, they will have attacked Burundi, and each Burundian must stand up to fight them," Nkurunziza said in a speech broadcast on state radio.
"The country will have been attacked, and we will fight them."
The 54-member African Union gave Burundi a four-day deadline on December 17 to accept a 5,000-strong force to halt months of violence, pledging to send troops even though Burundi said it was opposed to an "invasion force".
The small central African country descended into bloodshed in April when Nkurunziza announced his intention to run for a controversial third term in a July election that he went on to win.
"You cannot send troops to a country if the United Nations Security Council has not accepted it... the UN resolution says the international community should respect the independence of Burundi," Nkurunziza said in one of his strongest speeches yet following the unrest.
Burundi is still recovering from an ethnically-charged civil war between majority Hutus and minority Tutsis, which cost an estimated 300,000 lives between 1993 and 2006.
Hundreds of people have been killed since April, when opponents of Nkurunziza's re-election bid took to the streets in protest.
"When there are two warring forces then you can have a peacekeeping force," Nkurunziza said. "But this is not the case here, because we are facing a security problem. It is not a political issue, because this was resolved by the elections."
Earlier this month UN Secretary-General Ban Ki-moon said that deploying UN peacekeepers to Burundi was an option to quell the violence.
AU Commission chief Nkosazana Dlamini-Zuma has written to the UN Security Council asking for "full UN support including the authorisation of a support package" for the force, the AU has said.
The proposed force, the African Prevention and Protection Mission in Burundi, is known by its acronym in French, MAPROBU. No details of possible troop contributing nations have been given, or any timeline for its deployment.
Burundian troops themselves are a key contingent in the AU force in Somalia, AMISOM, as well as the UN mission in Central African Republic (CAR).
This comes just a day after the chairperson of the Commission of the African Union (AU), Dr Nkosazana Dlamini Zuma, warned the belligerent parties in Burundi that they could be subjected to severe sanctions should either party jeopardise the peace talks.
