The report said, many demonstrators gathered in front of the Israeli Consulate General in the Levent neighborhood on the European side to denounce the attack.
Protesters urged the international community to intervene and stop the Israeli attacks on Palestinian civilians.
Demonstrations also occurred in the Sariyer district, home to the U.S. Consulate General.
A banner bearing the message “Free Palestine” was unfurled, and the group chanted, “Down with Israel, collaborator U.S.”
Another group gathered in Sarachane Park in the Fatih district, where they prayed for the civilians who lost their lives.
At least 40 people were killed on Sunday evening in Israel’s bombing of tents of Palestinians in northwestern Rafah, the southernmost city of the Gaza Strip.
