At least 62 Palestinians have been killed in Gaza on Thursday since dawn, following a barrage of Israeli attacks on the besieged enclave, according to Al Jazeera and Palestinian media.
Israeli fighter jets bombed Gaza City's Shujaiya neighbourhood, targeting a family home and killing at least nine Palestinians.
Scores of people were also killed in al-Mawasi near Khan Younis, as well as the city itself, after Israeli bombs struck tents housing those displaced.
Gaza's health ministry reported at least 97 people killed in Israeli strikes in the past 24 hours.
Israel launched a renewed onslaught on the enclave on 18 March, ending a fragile ceasefire. Israel has killed over 1,000 Palestinians since, with the death toll rising every single day.
In Rafah, hundreds of thousands of fleeing Gazans sought shelter on Thursday in one of the biggest mass displacements of the war, as Israeli forces advanced into the ruins of the city, part of a newly announced "security zone" they intend to seize.
Rafah "is gone, it is being wiped out," a father of seven among the hundreds of thousands who had fled from Rafah to neighbouring Khan Younis, told Reuters via a chat app.
"They are knocking down what is left standing of houses and property," said the man who declined to be identified for fear of repercussions.
