.HAVANA (AP) – Cuban television on Tuesday showed the first images of Fidel Castro in six months, with a silent video of the ailing revolutionary chatting in a garden with visiting Venezuelan President Hugo Chavez. The 81-year-old Castro looked thinner, and his hair and beard appeared much whiter, in the latest video, which did not include audio. But he nevertheless looked vigorous and animated as he talked with Chavez and younger brother Raul Castro. He wore in a white track-suit jacket with red and blue trim.
