Israel-Gaza updates: 22, including 18 children, reported dead in Rafah strikes

A "small number" of Iran's surface-to-surface missiles landed in Israeli territory early Sunday morning, Israel Defense Forces Spokesman Daniel Hagari said.

One missile hit an IDF base in the south and a female child was injured.

Hagari said the Israeli Air Force has intercepted more than 10 cruise missiles outside of the country's territory. Over 200 missiles and UAVs (drones) were launched from Iran, he said.

The IAF remains in the air.

Meanwhile, a U.S. official confirmed to ABC News that U.S. forces in the Middle East had intercepted and shot down "a few dozen" Iranian objects headed toward Israel.

Britain's Defense Minister Grant Shapps said early Sunday morning local time that the U.K. is deploying "additional Royal Air Force" aircraft following Iran's attack on Israel.

"I have authorised the deployment of additional Royal Air Force assets. The RAF jets and air refuelling tankers will bolster our existing Operation Shader – the UK’s existing counter-Daesh operation in Iraq and Syria," Shapps' statement read. "In addition, these jets will intercept any airborne attacks within range of our existing missions, as required."

Following the news of the RAF deployment, U.K. Prime Minister Rishi Sunak said in a statement he "condemns in the strongest terms" Iran's attack on Israel.

"Iran has once again demonstrated that it is intent on sowing chaos in its own backyard," his statement read. "The UK will continue to stand up for Israel’s security and that all of our regional partners, including Jordan and Iraq.

"Alongside our allies, we are urgently working to stabilize the situation and prevent further escalation. No one wants to see more bloodshed."
