Yemen's President Ali Abdullah Saleh has returned to his country, amid protests that increasingly look like civil war. After fleeing to Saudi Arabia for treatment following an assassination attempt, Saleh returned the capital by private plane before dawn, according to Yemen TV. His return raises the risk of a full civil war. In his absence, Republican Guards led by his son, Ahmed, have been fighting army defectors and tribal fighters who have joined with the protesters. More than 80 people have been killed this week, mostly unarmed protesters.
