US President-elect Donald Trump's plan for a wall along the US-Mexico border isn't the only one raising controversy these days.
Construction began — and halted — last month on a wall at Ain al-Hilweh Palestinian refugee camp in southern Lebanon. The Lebanese army said the 6-foot-tall cement wall, which is intended to help keep terrorists and criminals from passing into and out of the camp, supposedly had the approval of senior Palestinian faction officials. But construction stopped when condemnation arose from numerous quarters.
