The two Canadians detained in a Cairo jail since August 16th may be facing a long list of allegations, including murder and intention to kill.  The Toronto Star is publishing a detailed list of intended charges authorities in Egypt are pursuing against John Greyson and Tarek Loubani.  The Star report says similar charges are also being sought for 140 Egyptians arrested during deadly demonstrations in the heart of Cairo.  The report says a handwritten document in scrawled Arabic ends with a thumbprint and the signature of Greyson.  Both men deny all the allegations.  Lawyers say there is no credible evidence against Greyson and Loubani and they should be released without charge.  The background to the allegations is the supposition that the pair participated in illegal demonstrations by supporters of the Muslim Brotherhood.
