The US has seized a sixth tanker in the Caribbean Sea in its ongoing efforts to control exports of Venezuelan oil, officials say. The vessel, Veronica, was boarded in a predawn operation 'without incident' as it was defying President Donald Trump's 'quarantine of sanctioned vessels', said the US military. 'The only oil leaving Venezuela will be oil that is coordinated properly and lawfully,' the Southern Command stated. Since US military strikes on Venezuela and the seizure of its president Nicolás Maduro this month, Trump has indicated plans to tap into the country's vast oil reserves. Veronica, a crude oil tanker sailing under a Guyanese flag, had departed empty from Venezuelan waters in early January, according to monitoring service TankerTrackers.com. The operation has been characterized by heightened coordination among various US agencies, with Homeland Security Secretary Kristi Noem affirming the flawless execution of the operation. The crackdown on the so-called dark fleet, which includes over 1,000 vessels transporting sanctioned oil, appears set to continue as the US government collaborates with Venezuela's interim leadership to regulate oil sales. The seizure coincided with discussions between Trump and opposition leader Maria Corina Machado, highlighting the intricate political landscape surrounding Venezuelan oil amidst ongoing sanctions and geopolitical strategies.
