An American oil company connected to Donald Trump is preparing to sink wells in remote Greenland despite not having received permission from the local authorities. As the US president renews his threats to claim the vast Arctic territory, materials to prepare for drilling were brought ashore in recent days on Greenland's eastern coast. That has prompted Greenland's government to issue a "strong warning" that no approval had been granted to land the kit. "All future logistical matters must be advised and approved by the mineral resources authority " before they are carried out," the government said in a statement. Two days later, Trump made his latest menacing post on Truth Social, showing himself looming over a Greenlandic village.
