CARACAS (Reuters) - Venezuela's opposition on Sunday warned that the government of President Nicolas Maduro may launch a political crackdown after his government accused adversaries of seeking to assassinate him with an explosives-laden drone.

State television on Saturday evening showed the socialist leader appeared startled by what appeared to be an explosion while he was giving a speech in downtown Caracas. Seconds later, the footage panned to hundreds of soldiers chaotically scurrying out of formation.
