FILE - This Oct. 6, 2007 file photo shows Cuban military cadets waving miniature Cuban flags and cheering outside the U.S. Interests Section in tribute to victims of the 1976 Cuba Airlines plane explosion in Havana, Cuba. The Cuban government erected the black flags behind to obscure an electronic billboard scrolling messages extolling democracy and human rights from the U.S. Interests Section.
