Argentina challenges UK in court over Falklands oil exploitation

Argentina's chancellor Quirno accuses the UK of illegally exploiting hydrocarbons in the Sea Lion basin and challenges it to prove its case in court, following Argentina's appeal to UNCLOS arbitration. This escalates the long-standing sovereignty dispute over the Falklands into a legal arena, potentially affecting energy investment in the region. The UK's response and the arbitration's progress remain uncertain.
