JIB JANINE, Lebanon (AP) — Grimacing, Mustafa Ahmad slid the scarred stump just below his right knee into his new prosthetic leg. Extending his arms for balance, he slowly rose and hobbled across the packed dirt floor toward the door of his ramshackle tent.

Wild-haired children peered through a gap in the plastic sheet that serves as the wall of his tent, trying to catch a glimpse of the procedure that finally fitted Ahmad with a prosthesis, more than two years after losing his leg during a bombing raid on his hometown in northern Syria.
