Valencia (AFP) – Venezuelan civilians learn how to shoot at a military barracks, as President Nicolas Maduro urges Venezuelans to join the civilian militia, which is linked to the armed forces, to help defend the country against what he considers a threat from the United States. Tensions between the two countries have soared in recent weeks after Washington ordered the biggest naval buildup in the Caribbean in years to target drug cartels. Venezuela has since hit out at the US for allegedly seizing a fishing boat for eight hours in its exclusive economic zone.
