Venezuela government, opposition in volatile test of strength

Venezuela's opposition and government head into a crucial test of strength Thursday with massive marches for and against a referendum to recall President Nicolas Maduro that have raised fears of a violent confrontation. Soldiers and police began taking up positions at strategic locations across the country Wednesday, ahead of what the opposition is billing as its biggest show of force yet -- dubbed "The Taking of Caracas" -- against the leftist government. Opposition leaders are hoping to put hundreds of thousands of people into the streets to demand quick action on a recall vote that Maduro has vehemently resisted.
