At least one U.S.-supplied bomb was used by Israel in a Thursday night airstrike that killed at least 22 people and wounded over 115 more in the Lebanese capital of Beirut, according to a Guardian analysis published on Friday.

The crisis, conflict, and arms division of Human Rights Watch and a former U.S. military explosives expert analyzed shrapnel from a bomb used by Israel in the strike on an apartment complex in the densely populated Basta neighborhood near central Beirut and concluded it came from a joint direct attack munition (JDAM) manufactured by Boeing.

“The bolt pattern, its position, and the shape of the remnant are consistent with the tail fin of a U.S.-made JDAM guidance kit for MK80-series air-dropped munitions,” HRW senior researcher Richard Weir told The Guardian.

Analysis by arms experts of shrapnel found by the Guardian at the strike scene was consistent with a US-produced JDAM, a guidance kit that converts large dumb bombs into GPS-guided missiles.

JDAMs have been key to Israel's war on Gaza and Lebanon
