Sudanese opposition¹ activists² have said a video which apparently³ shows election officials stuffing ballot⁴ boxes proves their claims of poll rigging.

苏丹反对派分子称，他们已经发现一段明显的作弊选举视频，该视频显示选举官员向投票箱中塞选票。

The clip, which has not been independently verified（验证，查清） , has been posted on the internet and is being circulated by a coalition⁵（联合，结合） of campaign groups.

The National Elections Commission (NEC), however, dismissed it as a fake and is not even investigating it.

The elections were held under a deal to end a 21-year north-south civil war.

The presidential, parliamentary and regional polls were the first multi-party elections since 1986.

Results are expected this week, after the elections were extended by two days due to organisational problems.

Several opposition parties withdrew in the north, saying President Omar al-Bashir's National Congress Party was trying to rig（装配，操纵） the voting.

On Tuesday, the US said the elections were plagued（折磨，困扰） by "serious irregularities（谬误，不规则） " and more should have been done to prevent them.

An election monitoring group earlier told the BBC it suspected that one of its observers had been kidnapped and beaten in the semi-autonomous（自治的，自主的） south.

'No complaint'

The video, which was posted on the video sharing website YouTube and which is impossible to verify independently, was apparently filmed in the eastern Red Sea state.

It shows people wearing the distinctive⁶（有特色的，与众不同的） orange bibs of election officials and traditional white gowns seemingly stuffing ballot boxes.

It has been circulated by the Sudan Democracy First Group - a coalition of trade unions and activists.

"This video is proving everything we said that the elections are rigged and they rigged the boxes," opposition Communist Party official Siddig Youssef told the Reuters news agency.

The presidential candidate of the opposition Popular Congress Party (PCP), Abdallah Deng Nhial, described the video as "scandalous（诽谤性的，可耻的） ".

"It's forgery⁷（伪造） , of course, done by the ruling party. They changed the boxes with already filled boxes. They brought them by cars from outside."

However, National Elections Commission member al-Hadi Mohamed Ahmed told reporters that no complaint had been received.
