The announcement that the mission will finish by Sept 2012, has been probably the cause of this boom in their use:
The devices have been the insurgents’ preferred weapon for several years, but their use rose 14 per cent year-on-year, in the second quarter of 2011.
Improvised explosive devices (IEDs) caused the majority of Nato casualties in 2010 and their indiscriminate use has been blamed by the United Nations for contributing to record civilian casualties.
From April to June, 3,845 exploded or were found, according to the Pentagon’s Joint IED Defeat Organisation (JIEDDO). Coaliton killed and wounded from the bombs rose 15 per cent yearly to 1,248 over the same period.
In June, use of roadside bombs was 25 per cent higher than average.
Most of the bombs are of homemade explosive, but attempts to block the import of ammonium nitrate fertiliser used in its manufacture have failed to stop the increase in devices.
