US Southern Command Kills Four in Caribbean Strike Under Operation Southern Spear

The U.S. Southern Command struck a vessel in the Caribbean Sea on Wednesday, March 25, 2026, killing four people on board in the latest operation under the military campaign known as Operation Southern Spear. SOUTHCOM announced the strike on the social network X, stating that intelligence had confirmed the vessel "was transiting along known narco-trafficking routes in the Caribbean and was engaged in narco-trafficking operations." The command described the targeted vessel as being operated by Designated Terrorist Organizations. No U.S. military personnel were injured in the operation, according to the SOUTHCOM statement. The strike was conducted at the direction of Gen. Francis L. Donovan, who has commanded SOUTHCOM since February 5, 2026.

163 dead since September as toll mounts The March 25 strike brought the total death toll from Operation Southern Spear to at least 163 (people killed) — total deaths under Operation Southern Spear since September 2025 since the campaign began in September 2025, across more than 45 strikes in the Caribbean and Pacific. The Guardian reported that the previous Friday's strike in the eastern Pacific — the 40th announced since the operation began — had already brought the toll to at least 159 before Wednesday's attack. SOUTHCOM has framed the campaign as applying "total systemic friction on the cartels," a phrase repeated in multiple official statements. The Trump administration designated drug cartels and other criminal groups as foreign terrorist organizations via executive order signed by President Donald Trump at the start of his second term in January 2025. The operation covers the area of responsibility of SOUTHCOM, which spans Latin America and the Caribbean.

The United States launched Operation Southern Spear in September 2025, targeting vessels in the Caribbean Sea and the eastern Pacific Ocean that U.S. forces described as involved in narcotics trafficking. The campaign followed President Trump's executive order designating drug cartels as foreign terrorist organizations at the start of his second term. On January 3, 2026, U.S. forces captured former Venezuelan president Nicolás Maduro and his wife, Cilia Flores, transporting them to the United States on drug trafficking charges. According to a 2020 report by the U.S. Drug Enforcement Administration cited by The Guardian, 74% of cocaine reaching the United States arrived through the Pacific, while only 8% came from fast boats from the Caribbean.

UN condemns strikes as extrajudicial killings without evidence The legal basis for the strikes has drawn sustained criticism from international bodies and legal experts. The United Nations and other humanitarian organizations have condemned the attacks as extrajudicial killings, according to multiple reports. The Trump administration has not presented concrete evidence that the targeted vessels were in fact carrying drugs, a point noted consistently across reporting by Reuters, The Guardian, and Portuguese and French outlets. The legality of the campaign has sparked debate within the U.S. political class and among international law experts, according to multiple sources. SOUTHCOM's statements have relied on intelligence assessments rather than publicly verifiable evidence when announcing each strike. The Guardian noted that it had reached out to the White House for comment on the latest strike.

Donovan leads command as regional pressure intensifies Gen. Francis L. Donovan, a United States Marine Corps general who assumed command of SOUTHCOM on February 5, 2026, has overseen the campaign's most recent phase. Donovan previously served as vice commander of the United States Special Operations Command from 2023 to 2026, according to his registry entry. The operation has unfolded alongside broader U.S. pressure on the region, including the January 3, 2026, capture of Nicolás Maduro, the former Venezuelan president, who was transported to the United States and charged with drug trafficking. The combination of military strikes and the Maduro capture has significantly elevated U.S. military engagement across Latin America and the Caribbean. Wednesday's strike was one of several announced in rapid succession, with SOUTHCOM sharing video footage of the targeted vessel before an explosion, according to reporting by Aktuálně.cz.
