As Sudan prepares for national elections set for April 11, tensions are rising as some opposition groups call for a postponement of the poll date and threaten to boycott the vote.  

They claim that it is not the right time to hold elections as many candidates have not been given the fair opportunities to carry out a significant electoral campaigns in the volatile country.  

But Omar al-Bashir, the president, has accused authorities in the previously independent south of obstructing his campaign efforts.

He has warned that a boycott could result in the cancellation of next year's referendum on independence for South Sudan.
