Burundi's controversial parliamentary and communal representatives elections kicked off early Monday morning despite a tense weekend of shelling in some parts of Bujumbura as well as the country's National Assembly speaker announcing that he had fled the country.

Pie Nitavyohanyuma announced Sunday that he had left Burundi for Belgium and called on president Pierre Nkurunziza to step down.

“It is never too late for president Nkurunziza to step down he must think of it, the seeking of another term is unconstitutional and it was very clear,” he said from Belgium, where he met Burundi's second vice president Gervais Rufyikiri who had also fled earlier last week.

Burundi's opposition has boycotted the poll citing the government’s failure to postpone the poll as the East African Community (EAC) and the African Union (AU) had recommended.

The AU became the latest body to withdraw its observer mission in the Burundi's electoral process after the European Union (EU).

The newly appointed UN inter-Burundi dialogue facilitator, Abdoulaye Bathily, said that after four days of dialogue, only the opposition had agreed on the postponement of elections as a conditions to hold free and fair polls.

“Our role is to facilitate not to impose any view. It was necessary to postpone the elections for one month as EAC and AU recommended. However, the Burundian government were not able to accept any postponement,” he said.

“We have made a report and we will be sending it to the (UN) secretary general; And with no dialogue, the country could be at the brink of getting back to instability,” he added.

Fear

However there is fear among many Burundians around Bujumbura even as they went to the polling stations to cast their votes.

“I am not going to vote right now because many others are not going so I will have to wait and see if I see there is big number of voters then I will go as well,” said a cyclist in Bujumbura.

After over an hour of opening, an electoral commission official said that at least 20 people had turned out at the polling station in Jabe, one of the areas most affected by protests and shelling over the weekend.

Two people were killed Saturday night after heavy gunfire in the Jabe suburb.

“The attacks were carried out by some groups of criminals in communes. A man who was trying to detonate a grenade failed and the same grenade exploded and killed him. What we understand is that these are attacks in areas where protests have been happening,” Burundi's deputy police spokesman Pierre Nkurikiye told The EastAfrican.

Mr Nkurukiye said that at least 6 police men were injured in the weekend attacks.

In another suburb (Nyakabiga), protests were observed late on Saturday night when residents took to the streets blowing whistles while police and unknown armed groups exchanged gunfire.

“we have decided to protest because the Imbonerakure want to carry out surprise attacks in our areas while wearing uniforms,” said one of the protesters in Nyakabiga.

People have continued to flee to neighbouring countries for fear of insecurity. According to the United Nations High Commissioner for Refugees, one hundred and twenty seven thousand Burundians have been registered in neighbouring camps, with 62,000 in Tanzania, 45,000 in Rwanda, 10,590 in DR Congo, 8,855 in Uganda and 400 in Zambia.
