At least 350 Palestinians have been killed and more than 1,600 wounded since the beginning of the IDF operation in the Gaza Strip, Palestinian sources reported Monday night.
The United Nations Office for the Coordination of Humanitarian Affairs said that most fatalities were "civilian policemen."
It said that other fatalities included at least 20 children, nine women and 60 other unarmed civilians.
Among the casualties are five sisters from the Jabalya refugee camp who were killed in an air raid on their home early Monday morning, Palestinian reporters in the Gaza Strip said.
They said the five sisters were from the Ba'lousheh family. They were identified as Jawaher, four; Dina, eight; Samar, two; Ikram, 14; and Tahrir, 17.
Their mother, Samira Abu Bakr, was lightly wounded during the raid.
