Before the mosques:
In a synchronized act of terrorism on January 29, 2006, seven churches were attacked – six by car bombs and a seventh, St. Joseph, in the banking district of Baghdad, by explosives which caused no damage. Five of the churches are located at various parts of Baghdad and the other two in Kirkuk, northern Iraq. There were a number of casualties among Christians and passer-by Muslims.
