John Kirby, the White House National Security spokesperson, stated that the administration of U.S. President Joe Biden is concerned about new reports that Israel used white phosphorus munitions supplied by the United States in an attack on Lebanon.

The American spokesperson said - in statements reported by the American newspaper "The Hill" - "We have reviewed the reports about that, and we are certainly concerned about it," confirming "We will investigate the matter to try to learn more."

He added, "I think it is important to remember that white phosphorus has a legitimate military purpose... And clearly, any time we provide materials like white phosphorus to another army, we fully expect it to be used in accordance with those legitimate purposes and in compliance with the laws of armed conflict."

The American newspaper (The Washington Post) reported today, Monday, that Israeli forces used white phosphorus supplied by the United States in the October attack in southern Lebanon, which resulted in at least nine civilians being injured.
