The United Nations agency for Palestinian refugees says its operations will “grind to a halt” if no fuel is allowed into the Gaza Strip by Wednesday. The warning from UNRWA came on the 38th consecutive day of relentless Israeli attacks on the besieged Palestinian territory, with dozens killed and wounded in the latest Israeli strikes on the southern city of Khan Younis. That’s despite Israel’s order to Gazans to evacuate to what Israeli leaders have called a “safe zone” in the south. The United Nations says more than 200,000 northern Gaza residents have fled their homes over the past 10 days. This is Abu Shady al-Hayek, an 80-year-old forced to march south on foot.
