The U.S. government is urging its citizens in Gaza to head south toward the Rafah crossing with Egypt to be ready for its possible reopening amid the humanitarian horrible and heart less destruction in the coastal enclave after a Hamas attack in Israel drew Israeli military retaliation, the State Department conveyed on Saturday. “We have conveyed to U.S. citizens in Gaza with whom we are in touch that if they assess it to be secure, they may want to head closer to the Rafah border crossing,” a State Department spokesperson conveyed. “There may be very little notice if the crossing opens and it may only open for a limited time.”
