"Insurgents in Iraq killed more than 21,000 civilians and wounded another 68,000 people with homemade bombs over the past five years, according to newly released data from the Pentagon.
The highest number of casualties came in 2007, coinciding with the worst sectarian violence and the surge in U.S. military forces to quell it. In that year, 7,295 people died — nearly 20 a day — from improvised explosive devices, says the Pentagon. Another 21,970 Iraqis were wounded.
The devices include roadside bombs, car bombs and suicide bombers."
