The UN’s humanitarian agency (OCHA) says the slain aid workers include a staff member of MSF and two with the Palestinian Red Crescent Society (PRCS), Al Jazeera reports.

They are Hussam Al Loulou and Mahdi Muhammad Muhammad Abu Subaih and his wife Samira Ismail Ahmad Abdul Hadi.

Their killings bring the total number of humanitarian staff killed since the war on Gaza to at least 412.

OCHA also noted that three Palestinian journalists have been killed in Khan Younis in two separate incidents on April 6 and 7.

In the April 6 attack, Islam Maqdad, a female journalist, was killed along with seven others, including women and children. And in the April 7 attack, during which Israeli forces bombed the media tent near Nasser Hospital, Helmi al-Faqawi burned to death while Ahmed Mansour succumbed to his wounds a day later.

Their deaths take the number of media workers killed in Gaza to at least 208.

The Palestinian Journalists Syndicate said another seven journalists were killed by Israeli forces in March, six of whom were in the field and another who was in his home.
