The US has pledged $1bn (740m) in assistance to Colombia, after the country's new right-wing president was sworn in on Friday. Abelardo de la Espriella, an ally of US President Donald Trump, used his maiden speech to promise an "all-out war" on what he calls "narco-terrorism". The US state department announced the financial support as part of a "security package" to help de la Espriella achieve "our shared goals", which include fighting organised crime and illegal immigration.
