Israel-Gaza updates: Death toll in Rafah airstrike rises to 50: Action Aid UK

Palestinian medic sources tell ABC News that at least 25 people are dead following a strike in northwest Rafah on Sunday night, near the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) headquarters there.

The area is densely populated with tents for internally displaced people, the sources said.

In a statement, the Palestine Red Crescent Society claimed "Israeli aircraft have shelled several tents in this area," resulting in injuries and deaths.

"Many have been transported to the Tal Al-Sultan clinic and the field hospitals near the sea in Rafah. Currently, numerous individuals remain trapped under the flames and in the tents destroyed by the bombardment," the organization said in its statement.

ABC News has reached out to the Israel Defense Forces for comment.

Sirens sounded in Tel Aviv on Sunday for the first time in months as Hamas' armed wing confirmed it launched a rocket attack on Israel's largest city.

Hamas' armed wing, the Al-Qassam Brigades, released a statement saying it had launched a rocket attack on Tel Aviv from Rafah.

"We bombed Tel Aviv with a large rocket barrage in response to the massacres against civilians," the statement said.

The Hamas fighters also posted an accompanying video showing what appeared to be rocket trails in the sky.

Israel Defense Forces said sirens sounded across central Israel Sunday after "eight projectiles were identified crossing from the area of Rafah into Israeli territory.

"A number of the projectiles were intercepted by the IDF Aerial Defense Array," the IDF statement said.

Israel's National Emergency Medical Service (MDA) said it received no reports of serious injuries.

"Following the Red Alert sirens heard in the center of the country: MDA teams did not locate casualties at any of the scenes, except for a patient who was lightly injured on the way to the protected space, and a number of victims with stress symptoms," the MDA said in a statement.

The IDF said later Sunday that it conducted an airstrike on the area where rocket launchers were used to direct rockets toward Tel Aviv, which the IDF said in a statement was "situated near two mosques in the area of Rafah."

Hamas has launched rocket attacks toward the areas around Gaza throughout the war but has not launched longer-range rockets in months. Sirens had not sounded in Tel Aviv in four months from Gaza-related rocket attacks.

A Hamas spokesperson alleged an unknown number of Israeli soldiers were captured and killed Saturday, however, Israeli Defense Forces (IDF) has denied the claim.

The spokesperson claimed Hamas fighters "lured" Israeli soldiers into a tunnel in Jabalia camp in the north of Gaza, subsequently "killing, capturing, and wounding" all of the soldiers involved.

In a short video, posted by Hamas' armed wing the Al Qassam brigades, an unmoving soldier is filmed being dragged along the floor. Images of weapons and gear are also shown.

The IDF denied the claim in an updated on X Saturday, saying, "The IDF clarifies that there is no incident in which a soldier was abducted."

ABC News has not been able to independently verify the video.

Four U.S. Army vessels that were part of the JLOTS temporary pier mission bringing humanitarian aid to Gaza broke free Saturday from their moorings because of rough seas and ended up beached near the pier in Gaza and near Ashkelon, Israel, U.S. Central Command said.

"Efforts to recover the vessels are under way with assistance from the Israeli Navy," Central Command said in a statement.

No injuries were reported and no U.S. personnel will enter Gaza during the recovery efforts, according to Central Command.
