Indian activists try to break through a police barricade as they are sprayed by a police water cannon during a protest in Thiruvananthapuram on February 8, 2013. Riot police fired water cannons at hundreds of protesters in the Indian state of Kerala demanding the resignation of a lawmaker over allegations he raped a schoolgirl 17 years ago. P.J. Kurien, 72, the deputy speaker of the state's upper house, was acquitted of rape in a trial in 2005 but he has come under new pressure after his accuser demanded a fresh probe in the wake of the storm over a deadly gangrape in Delhi in December.
