Israeli airstrikes across Gaza killed dozens more Palestinians on Wednesday, according to local officials. They said strikes on a U.N. school being used as a shelter and two homes killed at least 34 people, including 19 women and children.

Gaza’s Health Ministry says over 40,000 Palestinians have been killed in Gaza since the Israel-Hamas war began. It does not differentiate between fighters and civilians in its count. The war has caused vast destruction and displaced around 90% of Gaza’s population of 2.3 million, often multiple times.

Israeli military spokesman Rear Admiral Daniel Hagari said that the video of the tunnel was shown to the families of the hostages that are believed to have been killed. According to Hagari, it "was very hard for them to see how their loved ones survived in those conditions."
