I haven't heard the media mention "Blast-Lung Injury" at all but presumably some of the casualties in Beirut have this condition and presumably some have sadly died from it. Sometimes a casualty who has died with this condition can appear to have no external injury but the person's lungs have been destroyed by the blast from an explosion. There is only so much that the human body can take.
