An anti-government protester is detained by national guard after a small group of protesters clashed with guards at the end of a march in Caracas April 26, 2014. Venezuelan justice determined on Friday that Venezuelans who want peaceful protest must request permission from local governments to prevent the scattered forces, amid a wave of violent protests against President Nicolas Maduro.
