The General Accountability Office has released a report accusing Pakistan of blocking efforts to curb the smuggling of Improvised Explosive Devices (IEDs) into Afghanistan:
IEDs are the top killer of U.S. troops in neighboring Afghanistan, according the Pentagon’s Joint IED Defeat Organization. JIEDDO estimates that 83 percent of IEDs used in attacks on U.S. troops are made with fertilizers produced in Pakistan. IED attacks have increased slightly over the 12 months ending April 30, the most recent data available. There were 16,165 IED incidents over that period, a 2 percent increase.
While the majority of IEDs used in Afghanistan may be low-tech—made with fertilizers as JIEDDO notes—questions remain about the origins of other IEDs. Certainly, Iran has been smuggling weaponry to the Taliban. But, according to American servicemen deploying or recently deployed to Afghanistan, there is growing concern that China may be working with Pakistan’s Inter-Service Intelligence (ISI) to provide and perfect IEDs with the goal of testing new Chinese technology against American armor.
