Sudanese authorities have arrested Islamist opposition¹ leader Hassan al-Turabi, his family and senior members of his party have said.

苏丹伊斯兰教反对党领导人哈桑·图拉比的家属和其政党高级成员证实，苏丹当局已逮捕哈桑·图拉比。

Hassan al-Turabi was once a close colleague of President Bashir

His wife told the BBC she thought he was arrested for repeating in a newspaper interview his allegation（辩解，主张） that elections last month were rigged（作弊，非法操纵） .

President Omar al-Bashir was re-elected with 68% of the vote in Sudan's first multi-party vote in 24 years.

Mr Turabi's party was one of the few opposition groups that took part.

Sudanese officials have not confirmed the arrest.

Mr Turabi was once a close colleague of Mr Bashir but he lost out（输掉） in a power struggle between the two in 1999.

He has been imprisoned² or held under house arrest on several occasions, most recently for about two months early last year.
