At least six people have been killed and 20 others injured after an Israeli airstrike hit a building at Nasser Hospital in southern Gaza, according to officials from the Hamas-run civil defence agency.

The attack reportedly hit the hospital’s surgery department in Khan Younis early Thursday, November 12, 2026, causing extensive damage to the medical facility.

Mahmoud Basal, spokesperson for Gaza’s Civil Defence, disclosed the casualties, adding that a surgeon was among those killed in the attack.

The injured victims were reportedly receiving attention following the strike, while emergency responders continued recovery operations at the affected facility.

The Israeli military had not issued an immediate response to the incident, although it was contacted for clarification.

The attack has raised fresh concerns over the safety of medical facilities and healthcare workers in Gaza, where hospitals have repeatedly been affected by the ongoing conflict.

The Gaza Civil Defence agency operates under the Hamas-controlled Interior Ministry, with its emergency response activities receiving support from the International Committee of the Red Cross (ICRC).

However, independent verification of the reported casualties and circumstances surrounding the strike remains difficult, as Israel restricts international media organisations, including the BBC, from independently reporting inside the Gaza Strip.

The latest incident adds to the growing humanitarian concerns surrounding the conflict, particularly the impact of military operations on hospitals, patients and civilians seeking medical assistance.
