A US Marines' Lockheed Martin F35-B jet prepares to land at José Aponte de la Torre Airport, formerly Roosevelt Roads Naval Station, on September 13, 2025, in Ceiba, Puerto Rico. President Donald Trump is sending ten F-35 fighter jets to Puerto Rico as part of his war on drug cartels, sources familiar with the matter told AFP on September 5, as tensions mount with Venezuela over Washington's military build-up in the Caribbean. The planes will join US warships already deployed to the southern Caribbean as Trump steps up pressure on Venezuelan President Nicolas Maduro, whom the United States accuses of leading a drug cartel. The Trump administration recently carried out a drone strike in the southern Caribbean against a boat that had left Venezuela and was suspected of transporting drugs. Eleven people died in the attack. The president claimed that the vessel was operated by the Venezuelan gang Tren de Aragua. (Photo by Miguel J. Rodriguez Carrillo / AFP) (Photo by MIGUEL J.

(L-R) US Vice President JD Vance, US President Donald Trump and US Secretary of State Marco Rubio listen as Democratic Republic of the Congo Foreign Minister Thérèse Kayikwamba Wagner during a meeting with her and Rwandan Foreign Minister Olivier Nduhungirehe (not pictured) in the Oval Office of the White House in Washington, DC, on June 27, 2025. Rwanda and the Democratic Republic of Congo signed an agreement in Washington on Friday to put an end to a conflict in the eastern DRC that has killed thousands, although broad questions loom on what it will mean. Trump has trumpeted the diplomacy that led to the deal and publicly complained that he has not received a Nobel Peace Prize. But the agreement has also come under scrutiny for its vagueness including on the economic component, with the Trump administration eager to compete with China and profit from abundant mineral wealth in the long-turbulent east of the vast DRC.
