President Nicolás Maduro launched extended military exercises along Venezuela’s border with Colombia on Tuesday, drawing Washington’s attention amid rising friction between the South American neighbors. Maduro has come under mounting pressure from Colombia and the United States, which are among more than 50 nations that back opposition politician Juan Guaidó’s bid to oust the socialist president. Tensions spiked recently when Colombia and Venezuela accused each other of harboring hostile armed groups within their borders that are trying to overthrow the neighboring government.
