An Israeli strike on Nasser Hospital in southern Gaza killed at least six people overnight Wednesday and injured more than 50, according to Doctors Without Borders and Palestinian officials.

Doctors Without Borders said the strike hit the hospital’s operating area; Gaza’s Hamas-run health ministry said those killed included hospital workers, a doctor, patients and companions, while Israel said it had targeted a senior Hamas member.

Doctors Without Borders condemned the attack, saying there was no legal or moral justification for destroying a functioning hospital with patients and medical staff inside.

The organization described Nasser as southern Gaza’s last partially functioning hospital and a key care center for an estimated 1.3 million people; the reported casualty details could not be independently verified.

The strike comes amid continued deadly attacks despite a ceasefire in effect since October 2025, with Israel recently intensifying airstrikes it says target senior Hamas members.

The U.S.-led Board of Peace urged immediate implementation of Donald Trump’s peace plan, warning that civilians would otherwise continue to pay the price of further tragedies.

The Board of Peace called on Israel and Hamas to honor commitments to protect civilians, maintain the ceasefire and further demilitarize Gaza; Germany and other European countries have rejected the body as a rival to the United Nations.

The Gaza war began after the Hamas-led October 7, 2023, attack killed about 1,200 people in Israel and took 251 hostages; Gaza’s Hamas-run health authority reports that more than 74,600 Palestinians have been killed since.
