A Colombian court on Tuesday overturned the witness tampering conviction of influential ex-president Alvaro Uribe, who had been sentenced to 12 years' house arrest in a decision condemned by the United States.
The 73-year-old, who led a relentless military campaign against drug cartels and leftist guerrillas as president from 2002 to 2010, was found guilty in August of asking right-wing paramilitaries to lie about their alleged links to him.
