The Plot
The "plan of assassination was an elaborate and carefully considered one". Aziz had drawn up four plans to carry out the assassination, the first, was to kill him at the Mosul Rest House, the second, at his brother's house, the third, by an attack on Bakr's car on his way to Tel-Kutchuk and finally the master plan at the Military club where it was planned to entertain Bakr in the evening of the day of his arrival. Aziz Yamulki, then president of the club, was to give a secret signal and the assassination was to take place when the lights were to be put out.[1]
