Doctors Without Borders, known by its French acronym MSF, has condemned the Israeli attack on Nasser Hospital that killed a top Hamas leader and a 16-year-old boy, Al Jazeera reports.

The group said the attack late on Sunday showed a “total disregard for the protection of medical facilities, endangered patients and medical staff and the very provision of healthcare”.

It said several of its staff were present at the facility, which is the largest remaining functioning hospital in the Gaza Strip, at the time of the attack. One of them described panic among patients as the bombing took place.

“The distance between us and the explosion was so close that we could’ve been hit too,” said an MSF nurse who works in another ward in Nasser Hospital and was close by when the strike happened.

“Our colleagues, medical staff, patients and their caretakers were allterrified.”
