Zainab Alhusni was a simple seamstress in Syria, well-loved by all her neighbors and friends. Now, in a tragic turn of events, she has become a symbol of the cruelty gripping that conflict-wracked nation. Alhusni was only 18 when she stepped away from her Homs residence last month to buy groceries. Her family never again saw her alive. She was whisked away by Syrian security forces to coax the surrender of her activist brother, and ended up beheaded and dismembered, a neighbor, activists and human rights groups say.
