Troops in Afghanistan were attacked by 1,600 improvised explosive devices in June, a record in the decade long war.According to the National Journal, the number of attacks began increasing in May but are increasing as Pakistan allows a free-flow of bomb making materials across its borders.
This is just the most recent source of tension between Washington and Islamabad as IEDs caused 1,248 coalition casualties between April and June, a 15 per cent increase over last year.
Lt. General Michael Barbero told the National Journal that 84 per cent of IEDs use calcium ammonium nitrate fertiliser that’s produced at factories throughout Pakistan.
The U.S. is pressuring Islamabad to put stricter controls on the supply and transport, but Pakistan officials have so far refused.
“We’re never going to be successful in focusing on the battlefield in Afghanistan and focusing on the IED networks in Afghanistan,” Barbero said. “We’ve got to engage and do something about the source.”
Despite the deployment of double-V hull Strykers the roadside bombs are responsible 158 of the 283 battlefield fatalities in Afghanistan so far this year.
