Initially the blast trapped a number of U.S. soldiers. The driver of the suicide vehicle was driving northbound and stopped by a bridge support and detonated. There is a concerted campaign of cutting off bridges in and around Baghdad which can dramatically increase ground response time and movement of police and military units. Other bridges targeted have been two over the Diyala river, one in Taji, the Jadiriya bridge and the famous Sarafiya Bridge (pictured above). There have been attempts on critical spans like the Sarha Bridge, near the town of Tuz Khurmato on the Chinchal River, 150 kilometres north of Baghdad.
