At least 20 Israeli attacks in Gaza are highly likely war crimes with U.S.-supplied weapons involved, a U.S. think tank research says.

The Israeli military had used U.S. weapons for attacks on refugee camps, schools, and hospitals and in disproportionate attacks on military targets.

All are almost surely in violation of international humanitarian law and have caused huge civilian casualties. This is according to a research report by the Quincy Institute for Responsible Statecraft on Monday.

Israel relies on U.S. weapons, which are involved in nearly every facet of Israel’s military campaign, the research showed.

Israel used U.S.-made aircraft like F-35, F-16, and F-15 to drop U.S.-made bombs, including MK-84, MK-83, MK-82, and 250-pound “small diameter” bombs.

According to the report, this can be fitted with U.S.-made Joint Direct Attack Munition (JDAM) guidance kits.

As of Wednesday, the Israeli military has been expanding operations in the West Bank.

The Israeli attacks in the Gaza Strip have so far claimed more than 40,400 lives, according to local health authorities.
