The number of Palestinians killed rose to 28 in raids Tuesday by Israeli forces on the Gaza Strip, including 10 children and a woman, according to the Palestinian Health Ministry.
It said the number of injuries climbed to 152.
The ministry put the number killed at 26 on Monday. One of the children killed was a 10-year-old girl and the others were boys of various ages, according to the ministry.
Israeli warplanes launched raids beginning late Monday in separate areas of the Gaza Strip in Operation Guardians of the Wall.
The army announced Tuesday that it targeted 130 sites and assassinated 15 Hamas activists, since the start of its incursion on the Strip.
Tensions moved to Gaza after Palestinian factions gave Israel a deadline of 1500 GMT Monday to withdraw soldiers from the Al-Aqsa Mosque and Sheikh Jarrah neighborhood in occupied Jerusalem and release detainees.
