At least 42 people were killed in Israeli attacks on districts of Gaza City in the north of the strip on Saturday, the director of the government media office said.
One Israeli strike on houses in Al-Shati, one of the Gaza Strip's eight historic refugee camps, killed 24 people, Ismail Al-Thawabta told Reuters. Another 18 Palestinians were killed in a strike on houses in the Al-Tuffah neighborhood.
The Israeli military released a brief statement saying: "A short while ago, IDF fighter jets struck two Hamas military infrastructure sites in the area of Gaza City."
It said more details would be released soon.
