DRESDEN, GERMANY - APRIL 13: Supporters of the German anti-Islam movement Pegida attend a weekly Pegida demonstration on April 13, 2015 in Dresden, Germany. A large number of supporters and opponents are expected to attend the rally, which will feature Dutch right-wing politician Geert Wilders as a guest speaker. The Pegida movement, which originally emerged as a grass-roots effort with aims to curb immigration, among other issues, splintered into two camps earlier this year and the movement is seeking to regain its earlier momentum.
