“The weapon that left dozens of children dead on August 9 was a 500-pound (227 kilogram) laser-guided MK 82 bomb made by Lockheed Martin, one of the top US defense contractors.
The bomb is very similar to the one that wreaked devastation in an attack on a funeral hall in Yemen in October 2016 in which 155 people were killed and hundreds more wounded … In March of that year, a strike on a Yemeni market — this time reportedly by a US-supplied precision-guided MK 84 bomb — killed 97 people.” CNN: Bomb that killed 40 children in Yemen was supplied by the US.
