[11] Despite global outrage and calls from government officials from around the world to halt its Rafah offensive, less than 48 hours after the Tel al-Sultan massacre, Israel shelled the Al-Mawasi refugee camp in a designated civilian evacuation zone, killing at least 21 people, more than half of them women and girls.

[12] On 28 May, two days after the deadly Tel al-Sultan massacre,[13] a cluster of tents were hit by shells in the designated humanitarian zone of Al-Mawasi.

[14][15][16] Al Jazeera's reporter Hind Khoudary said: "Thirteen out of 21 people killed by Israel in the air strike on the so-called "safe area" of al-Mawasi were civilian women and girls".

[17][18] Following the attack, several aid organizations in this part of the city were forced to close their operations and move them to other parts of the Gaza Strip, including the Al Quds field hospital run by the Palestine Red Crescent Society, a clinic supported by Doctors Without Borders and kitchens run by the World Central Kitchen.

[19][20][21] Palestinians reported another assault at Al-Mawasi on 13 June, by Israeli navy boats firing heavy machine guns.
