A riot police officer stands in front of barricades as members of the Brahmin-Chhetri Society try to enter a restricted area while marching towards the constitution assembly building to protest against federalism in Kathmandu, May 27, 2012, as the midnight deadline of the nation's first federal constitution approaches. A new constitution is widely seen as crucial to helping end the instability that has plagued Nepal since the end of a Maoist-led civil war in 2006 and subsequent overthrow of the monarchy, but it has been thwarted by demands for the country to be divided into states along ethnic lines.
