The fires started around 1700 GMT and were caused by Israeli shells containing white phosphorous being launched across the border, Abdalla Mousawae, head of the Tyre Regional Center of Lebanese civil defense, told Reuters. The Israeli military did not immediately respond to a request for comment. Earlier this month, the Israeli military said an accusation by Human Rights Watch that it had used white phosphorus munitions in Gaza was "unequivocally false." White phosphorus munitions can legally be used on battlefields to make smoke screens, generate illumination, mark targets or burn bunkers and buildings. White phosphorus is considered an incendiary weapon under Protocol III of the Convention on the Prohibition of Use of Certain Conventional Weapons.
