Overall trends show a significant drop in violence over the last several months, according to previously unpublished military statistics obtained by NEWSWEEK. During a single week in mid-September, attacks in Iraq totaled about 900—down from about 1,700 a week in June. The number of attacks increased slightly in late September and early October during the Muslim holy month of Ramadan. But according to the statistics, the just-ended Ramadan holiday was significantly less violent this year than in the previous two years.
