For two months, the US military has been building up a force of warships, fighter jets, bombers, marines, drones and spy planes in the Caribbean Sea. It is the largest deployment there for decades.

Long-range bomber planes, B-52s, have carried out"bomber attack demonstrations" off the coast of Venezuela. Trump has authorised the deployment of the CIA to Venezuela and the world's largest aircraft carrier is being sent to the region.

The US says it has killed dozens of people in strikes on small vessels from Venezuela which it alleges carry"narcotics" and "narco-terrorists", without providing evidence or details about those on board.

The strikes have drawn condemnation in the region and experts have questioned their legality. They are being sold by the US as a war on drug trafficking but all the signs suggest this is really an intimidation campaign that seeks to remove Venezuela's President Nicolás Maduro from power.

"This is about regime change. They're probably not going to invade, the hope is this is about signalling," says Dr Christopher Sabatini, a senior fellow for Latin America at the Chatham House think tank.

He argues the military build-up is a show of strength intended to"strike fear" in the hearts of the Venezuelan military and Maduro's inner circle so that they move against him.

BBC Verify has been monitoring publicly available tracking information from US ships and planes in the region - along with satellite imagery and images on social media - to try to build a picture of where Trump's forces are located.

The deployment has been changing, so we have been monitoring the region regularly for updates.

As of 23 October, we identified 10 US military ships in the region, including guided missile destroyers, amphibious assault ships and oil tankers for refuelling vessels at sea.
