A Palestinian man smokes a water-pipe next to a mural of late Palestinian leader Yasser Arafat, in the West Bank town of Jenin, Tuesday, Nov. 27, 2012. Palestinian authorities on Tuesday opened Yasser Arafat's grave and foreign experts took samples from his remains as part of a long-shot attempt, eight years after the iconic leader's mysterious death, to determine whether he was poisoned, as relatives and some political successors have claimed.
