Nope. There are isolated reports which are of doctors in Gaza saying they have a seen burns that they estimate to be white phosphorus but (a) it's their guess it could be from any number of munitions/explosives (b) phosphorus used legally in flares could cause injuries if they fall unspent (c) Gaza doctors like everyone under Hamas rule cannot speak freely to press.

The reports from Lebonon are isolated incurred that are highly inclusive too. Plus this accusation is used as part of the anti-Israel "genocide" narative that Israel simply wants to harm Gazans/Palestinians civilians, but why on earth even according to this beer particular view would it use white phosphorus as a munition in Lebanon?
