National guard disperses water cannons on anti-government protesters during a protest at Altamira square in Caracas

The national guard disperses water cannons on anti-government protesters during a protest at Altamira square in Caracas March 14, 2014. Venezuela’s foreign minister lambasted U.S. Secretary of State John Kerry on Friday as a “murderer” fomenting unrest that has killed 28 people in the South American OPEC member nation. Since street demonstrations began against President Nicolas Maduro’s socialist government in early February, Venezuelan officials have been accusing Washington of stirring the country’s worst political troubles in a decade.
