A supporter of Venezuela's President Hugo Chavez holds a picture of him as she takes part in a gathering at Plaza Bolivar in Caracas February 18, 2013. Chavez made a surprise return from Cuba on Monday more than two months after surgery for cancer that has jeopardized his 14-year rule of the South American OPEC member. The 58-year-old socialist leader underwent a six-hour operation in Cuba on December 11 and had not been seen or heard in public until photos of him were published on Friday.
