Pope Francis expressed concern Sunday over escalating violence in the Middle East and prayed the situation doesn't lead to an "even greater war conflict."

During his noontime prayer in St. Peter's Square at the Vatican, the pope said, "I am following in prayer and concern, even sorrow, the news that has come in the recent hours of the worsening of the situation because of intervention by Iran."

"I make a heartfelt appeal for a halt to any action that could feed a spiral of violence with the risk of dragging the Middle East into an even greater conflict," Pope Francis said.

Iranian President Ebrahim Raisi claimed Sunday that Iran had taught Israel a lesson and warned of a "heavier" response to "any new adventures against the interests of the Iranian nation."

Iran said Israel was targeted in retaliation for its strike earlier this month on the Iranian Consulate in Damascus, Syria, that killed a top Iranian military leader.

"Following the instructions of Imam Khamenei, the Supreme Leader of the Islamic Revolution, and with the support of the proud nation and the powerful armed forces of Islamic Iran, I emphasize that any new adventure against the interests of the Iranian nation will be responded with a heavier and regrettable response from the Islamic Republic of Iran," Raisi said.

A 7-year-old girl injured in Iran's attack on Israel is reportedly the only casualty of the airstrikes, a spokesperson for the Israel Defense Forces said Sunday.

The girl was "severely injured by shrapnel," apparently from an intercepted missile, IDF spokesperson Daniel Hagari said.

"We wish her a speedy recovery," Hagari said. "Other than her, as far as we know, there are no additional casualties."

Iran launched 300 "threats of various types" at Israel on Saturday, Hagari said, including 170 unmanned aerial vehicles (UAVs), more than 120 ballistic missiles and over 30 cruise missiles.

Hagari said 99% of the threats launched by Iran at Israel were intercepted by Israel's Aerial Defense Array and Israeli Air Force fighter jets, as well as "the aerial defense systems and aircraft of our partners." The "few" ballistic missiles that weren't intercepted fell at Nevatim Air Force Base, causing only minor damage, Hagari said, adding that the base remains operational.

(Editor’s note: Earlier, the IDF said the child was 10, but the hospital updated the information to confirm she is 7.)
