Yemeni protesters take part in a demonstration outside the Saudi embassy in Sanaa against the death sentence on Shiite cleric and anti-government protest leader Nimr al-Nimr (portrait) in Sanaa, on October 18, 2014 after he was convicted by Saudi authorities of sedition. Amnesty International slammed the verdict as "appalling," dismissing Nimr's trial as "deeply flawed," and calling for the sentence to be immediately quashed.  The sentence is part of a campaign by Saudi authorities "to crush all dissent, including those defending the rights of the Kingdom's Shiite Muslim community," said Amnesty's Said Boumedouha.
