Portuguese authorities, in a joint operation between the Polícia Judiciária (PJ) and the Portuguese Navy, intercepted a semi-submersible vessel carrying over 1.7 tons of cocaine destined for the Iberian Peninsula. The operation, which occurred in the Atlantic Ocean, led to the arrest of four Venezuelan nationals who were the crew of the vessel. The arrests and seizure were announced via social media platforms by the Polícia Judiciária and Visegrád 24 on November 5th, 2025. The interception of the semi-submersible, described as belonging to a transnational criminal organization, was a significant blow to drug trafficking efforts. The seized cocaine was reportedly intended for distribution across the Iberian Peninsula. All four arrested individuals have been handed over to criminal courts for prosecution, as confirmed by the Polícia Judiciária's statement on November 5th. This development occurred within a broader context of aviation advisories for Puerto Rico, where a Notice to Airmen (NOTAM) issued on November 5th indicated potential outages of ADS-B, TIS-B, and FIS-B services until November 17th, 2025. These advisories coincided with reports of unidentified, strong radar signals emanating from the region, sparking discussions among aviation observers and defense tracking accounts. The exact cause of these radar anomalies remains undisclosed.
