no way in hell that explosion is from a "hacked pager", maybe explosive charges in the pagers? Mossad probably handed them out to their hezzbullah buddies
No way in hell those little batteries make an explosion like that, and other anon makes a good point, various levels of battery charge, but they all go off like a bomb.
Keep in mind, they don't want to kill a bunch of people, they want to wound a bunch of people to overwhelm hospitals and demoralize people, tell them they can hack their phone at any time and kill them. Mossad are the real terrorists
