Several explosions lit up the night sky above Gaza early Sunday after dozens of Palestinians were killed on their way to an aid distribution site hours earlier. At least 31 people were fatally shot when they were travelling to the site run by the Israeli-backed American organization Gaza Humanitarian Foundation near Rafah, hospital officials and witnesses said on Saturday. They also said that Israeli airstrikes in Deir al-Balah and Khan Younis on Saturday killed at least 28 Palestinians, including four children.
