JERUSALEM — Palestinians fled in a mass exodus from northern Gaza Friday after Israel’s military told some 1 million people to evacuate toward the southern part of the besieged territory, an unprecedented order ahead of an expected ground invasion against the ruling Hamas militant group.
The U.N. warned that telling almost half the Gaza population to flee en masse would be calamitous, and it urged Israel to reverse the order. Families in cars, trucks and donkey carts packed with blankets and possessions streamed down a main road out of Gaza City, the biggest city, as airstrikes continued to hammer the territory.
