Among the dead are two 13-year-old boys, three journalists and a woman.
One of the boys was killed, along with his father and a 22-year-old man, in a drone strike at the Bureij refugee camp, according to representatives of al-Aqsa Hospital.
The second boy was shot dead while collecting firewood in Bani Suheila, Nasser Hospital said.
"He left hungry this morning. He said he would finish it quickly and then come back," the boy's mother tearfully told the AP.
The Israeli military claims that one of the attacks was carried out after discovering several people flying a drone that posed a threat to Israeli soldiers.
The three Palestinian journalists were killed later Wednesday in an Israeli attack on the town of Zahraa. They were in the process of documenting a new refugee camp in the Netzarim area, according to the camp's Egyptian steering committee.
Over 470 Palestinians have been killed by Israeli forces since the ceasefire between Israel and Hamas came into effect on October 10, according to the Gaza Strip's Health Ministry.
