Iraq violence: Monitoring the surge

The US is becoming resigned to the fight against insurgency possibly lasting a decade or more.
Its head of forces in Iraq, Gen David Petraeus, told the BBC's John Simpson this week that the average counter-insurgency lasted nine or 10 years.
But he also suggested there was scope to reduce troop numbers as long as areas that the coalition had gained could be held by Iraqi forces.
The US says the surge is beginning to show signs of progress, with areas such as parts of Baquba now under American control.
However, Gen Petraeus says it could take until September to gauge its full effects.
During the seven-day period to 11 July there were some 575 violent deaths in the country - up by about 80 on the previous week.
Again, civilians bore the brunt of the violence with 377 deaths - topping last week's figure.
Military casualties, both American and Iraqi, were also up, as was the number of Iraqi police who were killed.
The BBC's Diplomatic Correspondent, Jonathan Marcus, says this reflects the dramatically increased level of US offensive operations.
However, the 51 reported deaths among insurgents were considerably lower than the previous week's 175.
