Why did Iran attack Israel? What to know about the strikes, U.S. response.

Iran launched a wave of missiles and drones toward Israel late Saturday as regional tensions continued to mount over the war in Gaza. President Biden condemned the attack and spoke with Israeli Prime Minister Benjamin Netanyahu to reiterate the United States’ “ironclad” commitment to Israeli security, the White House said. Other allies including Germany, Canada, France and Britain reaffirmed their support for Israel in the wake of the attack while expressing fears that Tehran’s assault could further destabilize the Middle East.

Iranian state media said the missile and drone assault was in retaliation to a deadly Israeli strike on an Iranian diplomatic compound in Syria on April 1, which killed members of the Islamic Revolutionary Guard Corps, including senior commander Mohammad Reza Zahedi and Brig. Gen. Mohammad Hadi Haj Rahimi.

Hamas expressed support for Iran’s attack on Israel this weekend, calling it a deserved response to the attack in Syria. Officials from the rebel Houthi group in Yemen congratulated Iran while downplaying their own involvement; Hagari said some UAVs and cruise missiles were launched from Yemen.

Israel has carried out strikes in Syria against Iran and its allies for years and throughout its six-month military campaign against Hamas in Gaza. But the April 1 attack stood out both because of its location — in a diplomatic compound, traditionally exempt from hostilities — and because of the seniority of the apparent targets.

The Israeli strike also frustrated Washington.

Three U.S. officials who spoke on the condition of anonymity to discuss security matters said Defense Secretary Lloyd Austin and other senior defense officials believed Israel should have informed them ahead of time because of the strike’s implications for U.S. interests in the region, The Washington Post reported.

U.S. officials worry about a multifront war breaking out and feared the Damascus strike could lead to attacks on U.S. military personnel based in Iraq, Syria or other parts of the Middle East.
