The US is preparing its largest single sale of 2,000-pound bombs to Israel, worth approximately $2.8 billion, in recent years, according to a Tuesday Washington Post report citing a US official.

The package will reportedly consist of 40,000 of the 2,000-pound bombs, including 20,000 MK-84s and 20,000 BLU-117s. The official told the Washington Post that the sale also included 20,000 I-2000 Penetrator warheads. 

According to the report, congressional committees have been informally notified of the pending transaction.

This is a developing story.
