A teenager was killed during a protest on Tuesday in the western city of San Cristobal, state officials said, as tensions rise in Venezuela amid an economic crisis and a government crackdown on the political opposition.

Jose Miguel Insulza, Secretary General of the Organization of American States (OAS), said on Friday that “the detention of the Mayor of Caracas, Antonio Ledezma, has caused alarm due to the way in which it took place and because it deals with an elected leader exercising his duties.”

Venezuelan intelligence agents arrested on Thursday opposition leader and Caracas metropolitan mayor Antonio Ledezma, witnesses said, after accusations he was involved in a coup attempt against President Nicolás Maduro.

Backers of jailed Venezuelan opposition leader Leopoldo Lopez took to the streets of Caracas on Wednesday on the first anniversary of his arrest and subsequent jailing, but the mood of last year’s mass protests against the government of President Nicolas Maduro was markedly different.

Venezuelan president Nicolas Maduro Thursday night went on the air and said the intelligence services had foiled a coup and arrested multiple people who were behind the attempt, which was backed by the United States.

Venezuelan police fired tear gas Thursday to break up students demonstrating against President Nicolas Maduro's government, on the anniversary of protests that eventually left 43 people dead last year.

Ratings agency Standard and Poor's on Monday downgraded Venezuelan long-term credit ratings to CCC from CCC+, citing falling oil prices and the government's failure to address economic distortions.

In a documentary that aired recently on the Canadian Broadcasting Corporation's popular The Fifth Estate program, an allegory of Vladimir Putin was presented. The wily Russian president was described growing up in a shabby St. Petersburg apartment, where he would often corner rats.

The Venezuelan government has turned down a request by former presidents of Chile and Colombia to visit opposition leader Leopoldo Lopez in jail. Chile's Sebastian Piñera and Colombia's Andres Pastrana say they are in Venezuela to support the opposition and have called for the release of Mr Lopez, who was arrested nearly a year ago.

In a three-hour State of the Nation speech to the National Assembly on Wednesday night, president Nicolás Maduro acknowledged some of the economic realities facing Venezuela: the economy contracted by 2.8% in 2014 and inflation stood at 64%.
