As bombs rained down on Beirut¡¯s southern suburbs, Ali Hussaini faced a heart-wrenching challenge: how to explain what was happening to his two partially deaf daughters.

¡°They would ask me what is going on? Why are we running away?¡± Hussaini said.

¡°When the bombs hit, I would try to move them away from the sound, but when they saw their siblings who can hear run towards us ... they would be puzzled,¡± he said.
