remain in Syria, where classrooms have been bombed, used as shelters or turned into military barracks. Another 300,000 Syrian children don’t attend school in
Lebanon, along with some 93,000 in Jordan, 78,000 in Turkey, 26,000 in Iraq and 4,000 in Egypt, UNICEF officials in Geneva said. Those numbers likely are higher, as
UNICEF can’t count the children whose parents didn’t register with the United Nations refugee agency. AP
