Israel-Gaza updates: IDF says officer and soldier injured in attack from Lebanon

At least 30 people were killed Sunday after Israeli strikes on two schools in Gaza City, according to the search-and-rescue organization Gaza Civil Defense.

The Israel Defense Forces confirmed Sunday that the Israeli Air Force executed an "intelligence-based strike' on Hamas command and control centers allegedly embedded within the Hassan Salame and Nasser schools in Gaza City.

"The schools were used by Hamas’ Al-Furqan Battalion as a hiding place for its terrorist operatives and as command centers used to plan and execute attacks against IDF troops and the State of Israel," the IDF said in a statement. "Prior to the strike, numerous steps were taken to mitigate the risk of harming civilians, including the use of precise munitions, surveillance, and additional intelligence."

The IDF accused the Hamas terrorist organization of violating international law by operating inside civilian infrastructure and "exploiting the civilian population as a human shield for their terror activities against the State of Israel."

After the assassination of Hamas leader Ismail Haniyeh, Hamas said it is in the process of selecting a new leader, saying the assassination "will only increase the strength of the Hamas movement and the Palestinian resistance," in a statement.

Hamas said it has convened urgent meetings following the assassination and will announce the new president once they are chosen.

At least 16 people have been killed in the Israeli strike on the Hamama School, according to the Gaza civil defense.

Israel has claimed that the school was being used as a "command and control" center by Hamas.

The U.S. Central Command Forces said it struck and destroyed one Iranian-backed Houthi land attack cruise missile in Yemen.

"It was determined the LACM presented an imminent threat to U.S. and coalition forces, and merchant vessels in the region. These actions were taken to protect freedom of navigation and make international waters safer and more secure," CENTCOM said in a statement Saturday.
