Israeli strikes on Nasser Hospital in Gaza on Monday (Aug 25) killed at least 15 people, including four journalists, one of whom worked for Reuters, Palestinian health officials said.

Cameraman Hussam al-Masri, a Reuters contractor, was killed in the first strike, according to the officials. Photographer Hatem Khaled, who was also a Reuters contractor, was wounded in a second strike, the officials said.

Witnesses said the second strike took place after rescue workers, journalists and other people had rushed to the site of the initial attack.

The Reuters live video feed from the hospital, which was operated by Masri, suddenly shut down at the moment of the initial strike, Reuters footage showed.

"We are devastated to learn of the death of Reuters contractor Hussam al-Masri and injuries to another of our contractors, Hatem Khaled, in Israeli strikes on the Nasser hospital in Gaza today," a Reuters spokesperson said in a statement.

"We are urgently seeking more information and have asked authorities in Gaza and Israel to help us get urgent medical assistance for Hatem," the spokesperson added.

The Israeli military and the Prime Minister's Office both had no immediate comment regarding the strikes.

Health officials in Gaza named the three other journalists as Mariam Abu Dagga, Mohammed Salama and Moaz Abu Taha. A rescue worker was also among those killed, they added.

Dagga freelanced for the Associated Press when the conflict in Gaza began, as well as other news outlets.

Salama was a photojournalist and cameraman for Al Jazeera. His death was confirmed by the news network.

The Palestinian Journalists Syndicate condemned Israel for the strikes, saying it represented"an open war against free media, with the aim of terrorising journalists and preventing them from fulfilling their professional duty of exposing its crimes to the world".

More than 240 Palestinian journalists have been killed by Israeli fire in Gaza since the war started on Oct 7, 2023, according to the Palestinian Journalist Syndicate.
