In a statement on Tuesday, Orascom Telecom said it was conducting a review of its operations in Burundi, Zimbabwe and the Central African Republic "to identify, examine and consider a range of strategic alternatives".

 

"Those strategic options include, but are not limited to, a sale of all or a material part of the Sub-Saharan African Operations either in one transaction or in a series of transactions," it said.

 

Russia's Vimpelcom took control of the Egyptian company last year in a deal worth around $6 billion.
