Shares in Orascom Telecom Media and Technology Holding rose more than four percent after trading in the stock resumed at midday on Tuesday following a statement from the firm saying it had not taken any decision regarding a sale of its Mobinil stake.
In a TV interview broadcast on Monday evening, Orascom Chairman Naguib Sawiris had said he intended to sell his company's 5 percent stake in Mobinil.

Mobinil is the brand name for the Egyptian Company for Mobile Services. France Telecom owns 94 percent of the company.
