American attempts to resolve Egypt's political crisis have fallen flat after the Muslim Brotherhood leadership refused to meet a visiting senior diplomat.
The attempt failed after each side deemed it too dangerous to meet in a venue of the other's choosing.
Gehad Addad, a party spokesman, said the proposal foundered after Mr Burns declined to visit the Brotherhood's protest camp in north-east Cairo.
"His people said it was too dangerous for him to come here," Mr Addad said. (© Daily Telegraph, London)
