Spies, drones and blowtorches: How the US captured Maduro

For months, US spies had been monitoring Venezuelan President Nicolas Maduro's every move.

A small team, including one source within the Venezuelan government, had been observing where the 63-year-old slept, what he ate, what he wore and even, according to top military officials, "his pets".

Then, in early December, a planned mission dubbed "Operation Absolute Resolve" was finalised. It was the result of months of meticulous planning and rehearsals, which even included elite US troops creating an exact full-size replica of Maduro's Caracas safe house to practise their entry routes.
