The United States has announced a new multi-billion dollar military package for Israel as the country continues its devastating military campaign against Palestinian civilians in the Gaza Strip.

On Tuesday, the U.S. State Department notified Congress of its approval for the sale of 50 F-15 fighter jets to Israel, valued at $18.82 billion. In addition, Israel will purchase around 33,000 tank cartridges, up to 50,000 explosive mortar cartridges, and new military cargo vehicles.

The State Department emphasized the U.S.’s commitment to Israel’s security, stating that assisting Israel in maintaining a strong self-defense capability is crucial to U.S. national interests. The F-15 fighter jets included in this package are produced by Boeing.

Overall, the Biden administration approved more than $20 billion in weapons sales to Israel on Tuesday, with some of the arms expected to be delivered immediately, according to the Pentagon.

This new military aid comes amid U.S. claims of supporting a ceasefire in Gaza, where Israel’s ongoing military offensive, backed by Washington, has led to the deaths of nearly 40,000 Palestinians, the majority of whom are women and children. The conflict has also resulted in over 92,000 injuries, with thousands more missing and presumed dead under rubble.

Concerns are growing over the potential for a broader regional conflict as Israel continues near-daily cross-border strikes in Lebanon and Yemen.
