Protesters, mostly workers, burn a mural depicting U.S. President Barack Obama and Philippine President Benigno Aquino III after being blocked by police from getting closer to the U.S. Embassy in Manila to mark International Labor Day Wednesday May 1, 2013 in Manila, Philippines. The workers, who have demanding wage increases for years, assailed Aquino for his Labor Day "gift" of non-wage benefits. The protesters have been clamoring for years for a P125-Peso ($3.125) across-the-board wage hike and condemn the Government's policy of outsourcing labor which allegedly eliminates job security.
