The wife of Sudan's ousted President Omar al-Bashir, Widad Babiker, has been summoned for questioning over possession of land and bank accounts, Arabic-language website Baj News reports.

Mrs Babiker who has been under house arrest since the ousting of her husband on 11 April was taken to the prosecution office on Thursday.
