Venezuela's sacked attorney general Luisa Ortega said Friday she had evidence that President Nicolas Maduro and his inner circle were implicated in the massive corruption scandal around Brazilian construction firm Odebrecht.

"They are very worried and anxious, because they know we have details on all the cooperation, amounts and people who got rich, and that investigation involves Mr Nicolas Maduro and his inner circle," Ortega told a meeting of Latin American prosecutors in Mexico by video conference.
