Egypt's stock exchange said it had suspended trading in EFG-Hermes shares on Tuesday, saying that it was seeking more details about the firm's Chief Executive Yasser El-Mallawany who faces a travel ban.

Airport authorities prevented Mallawany from traveling to the United Arab Emirates last week when officials found his name on a list of people banned from leaving.

The company said Mallawany was still carrying out his duties and that no charges of any form had been levelled against him.
