Seven schools sit within the lethal fragmentation zone of suspected large bombs

Seven craters consistent with 2,000-pound bombs were detected near seven schools in one area of northern Gaza. All the schools fall within the 365-meter (0.227-mile) lethal fragmentation zone — an area of exposure to injury or death — of the suspected bombs.

Note: CNN and Synthetaic analyzed and isolated craters 12 meters in diameter and larger, which experts said are consistent with underground explosions produced by 2,000-pound bombs in the light soil found in Gaza. To account for a margin of error, conservative measurements were used in CNN's crater count.
