Protesters, mostly workers, clash with riot police as they try to force their way closer to the gates of the U.S. embassy in Manila, Philippines to mark International Labor Day on Sunday, May 1, 2016. Among the demands are, better wages and salaries, an end to contractual labor, better working conditions and retirement benefits, less taxes, public and not privatized social services, and the assertion of national sovereignty against foreign domination and control.
