South Lebanon Sunday witnessed its deadliest day since the month-long Israel-Hizballah 2006 war when 10 Palestinian demonstrators were reported shot dead and another 112 wounded as Israeli troops opened fire on protests along the border fence. The casualties came as a massive crowd of Palestinians gathered at Maroun er Ras, a small hilltop village overlooking the border with Israel, to commemorate the 63rd anniversary of the Nakba, or Catastrophe, when the state of Israel was established.
