About 400 U.S. citizens along with their eligible family members are expected to begin leaving Gaza in stages Thursday through the Rafah border crossing into Egypt, the only official exit point not controlled by Israel, according to a U.S. official who spoke on the condition of anonymity to discuss a sensitive matter. Injured Palestinians, along with hundreds of foreign nationals and dual citizens, left the Strip on Wednesday. The same day, Israel launched another deadly attack on the Jabalya refugee camp, saying it was targeting Hamas operatives and infrastructure. At least 195 people have been killed in the strikes on the camp, Hamas said Thursday local time, while the United Nations said the attacks “could amount to war crimes.”
