In Iraq, Islamic State militants are kidnapping thousands of people at gunpoint to use as shields against the U.S. takeover as the militants move to their last stronghold of Mosul.   This is something that complicates the U.S. airstrikes because it is not certain how many civilians might be injured or killed since they are being used as shields by the militants.   As the militants are squeezed tighter and tighter together in their last stronghold, more and more villages are suffering, entire villages of people are being taken and used as these shields.   It is a terrible situation and I cannot imagine the suffering as people are missing and lost forever from families and leaving many children as orphans.
