An opposition demonstrator shouts slogans during a protest against President Nicolas Maduro’s government in Caracas February 16, 2014. Leopoldo Lopez, a Venezuelan opposition leader wanted by police in connection with deadly street protests told supporters via Twitter to keep demonstrating, but peacefully, and armed police visited his father’s home, apparently seeking to arrest him. The demonstrators have vowed to stay in the streets until Maduro resigns, although there is no sign of that happening. REUTERS/Jorge Silva (VENEZUELA – Tags: POLITICS CIVIL UNREST)
