Venezuela's re-invigorated opposition faces a crucial test Wednesday as it seeks to fill streets nationwide with protesters in an appeal to the military and the poor to shift loyalties that until recently looked solidly behind President Nicolas Maduro's socialist government.

Two days of massive protests on the streets of Caracas against the government of President Nicolas Maduro spilled into a violent night in several parts of the city, with residents in El Valle witnessing repetitive gunfire, street barricades set aflame and more than a dozen businesses looted.

At least five deaths have been blamed on the strong-armed response to protests that were triggered by the government-stacked Supreme Court's decision three weeks ago to strip the opposition-controlled congress of its last remaining powers after a year-long power battle.

After four torturous years of negotiations, a stunning referendum rejection, last-minute compromises and two signing ceremonies, Colombia has ratified a peace deal.

The loss by a razor-thin margin leaves leaders and citizens wondering if another peace deal is possible.

If the peace accord is accepted, the estimated 7,000 FARC fighters would have to turn over their weapons.
