The fresh air attacks have hit Sheikh Radwan district as well as a mosque and a center for the disabled on Saturday.
At least three girls with disabilities were killed when a strike hit the facility for the disabled in Beit Lahiya in northern Gaza.
Witnesses say a massive fire also broke out after a strike hit eastern Gaza.
Sources say Israeli warplanes have pounded nearly 160 targets over the past 24 hours.
A total of 130 Palestinians, most of them women and children, have lost their lives in the impoverished region since Tuesday. Over 900 others have been also injured in the ongoing deadly air raids.
This is while Israeli tanks have now lined up along the Gaza border, firing into the region. Tel Aviv has also mobilized some 33,000 reservists in preparation for a possible ground incursion.
Meanwhile, Palestinian resistance fighters have fired rockets into Israel in retaliation for attacks on the Gaza Strip.
According to latest reports, three rockets hit Dimona and three landed in Be’er Sheva in Israel’s south, critically injuring one person.
Four rockets have also hit Eshkol and three others targeted Israel’s central district. Sirens have been heard in the Eshkol Regional Council and Code Red alerts have been issued in Ashdod, Eshkol, Ashkelon, and Kiryat Gat in the south.
People in Iran, US, Jordan, Tunisia, Turkey, France, Indonesia and Britain have taken to the streets, calling for a halt on ruthless Israeli attacks.
