U.S.-made bomb used in Israeli strike on Rafah that killed dozens, munitions experts say

Analysis of images of shrapnel gathered at the scene of an Israeli strike in Rafah on Sunday showed evidence of a bomb that was a U.S.-made GBU-39, two munitions experts told CBS News. Dozens of Palestinians were killed in the strike and subsequent fires.( )

"I instantly knew the housing was a GBU," Trevor Ball, who worked as an ordnance disposal tech - or bomb diffuser - for the U.S. Army for five years, told CBS News. "I've seen a lot of them in this conflict, and I've even gone back and looked at past conflicts just to get an idea of what ordinance Israel has used in the past when I started looking into this, and it's a very distinct object, the GBU. It's a very unique round."( )

Photos and videos used to identify the bomb remnants were taken by journalist Alam Sadeq in Gaza, who visited the scene of the strike early on Monday.

He told CBS News he was searching the area, including around damaged tents that had once housed civilians, when he identified several pieces of shrapnel with English words on them.( )

He said he recognized the words from bomb remnants he had seen after a previous strike on a building in Gaza, so he gathered the fragments together in a pile and photographed them.

"The whole actuator assembly is unique," Ball told CBS News, explaining his identification process using the images of the shrapnel from the scene. "It's just not in other rounds."( )

Richard Weir, senior researcher in the Crisis, Conflict and Arms division at Human Rights Watch, agreed with Ball.

"One of the critical elements here, right, is… the tail section. Sometimes it's referred to as the control section or the actuator section, which moves the fins in the rear. That matches up directly with the GBU-39 small diameter bomb, which is U.S. made," Weir said. "It also matches with the idea of the description of the size of the warhead, in terms of the explosive weight."( )

Israeli military spokesperson Daniel Hagari said in a briefing on Tuesday that the Israeli strike on Rafah "was based on precise intelligence that indicated that these terrorists who were responsible for orchestrating and executing terror attacks against Israelis were meeting inside the specific structure we targeted."
