The official, speaking on condition of anonymity, said that as Israeli leaders seemed to approach a decision on a Rafah incursion, “we began to carefully review proposed transfers of particular weapons to Israel that might be used in Rafah” beginning in April.
“As a result of that review, we have paused one shipment of weapons last week. It consists of 1,800 2,000lb bombs and 1,700 500lb bombs,” the official said, according to Reuters. The Associated Press and Agence France-Presse reported similar comments from a senior US official.
Ukraine probably has no use for those, as whatever targets they’d want to bomb with those would be impossible to bomb without getting shot down. They’re only good against targets without air defenses.
