IRBIL - Research suggests the Islamic State group relies on commercially available components for most of its bombs, with some parts coming from as far away as the US or Japan.
A report released Thursday by the London-based Conflict Armament Research says most components --such as chemicals and detonators come from companies in Turkey and Iraq, which may not know the parts are being bought by the extremists.
Roadside bombs have long been a weapon of choice among insurgents in the Middle East. IS has pioneered the use of armored vehicles loaded with explosives, which can withstand gunfire in order to reach targets during battles.
The researchers traced the origins of over 700 components recovered from IS bomb factories and unexploded bombs. The parts they fully documented had all been legally acquired.
