White phosphorus is a special chemical. It's used in some weapons. When it burns, it makes a very bright light and a lot of smoke. It's one type of the chemical element called phosphorus.
White phosphorus is dangerous for people. It can cause serious burns if it touches skin. It can also be harmful if someone breathes in its smoke or accidentally eats it. Because it's so dangerous, it can cause serious health problems.
Using weapons that cause fires, like white phosphorus, against regular people (civilians) has been against international rules since 1949. Even so, it has been used in some conflicts. For example, U.S. forces used it in Iraq in 2004. The Israeli Army also used white phosphorus for smoke cover during a conflict in the Gaza Strip in 2008-2009.
