As U.S. and Iranian officials prepare to meet in Oman, U.S. military activity across the wider region has sharply increased, with new aircraft, ships, and drones moving into position around the Gulf, according to verified reports. Satellite imagery shows at least a dozen U.S. F‑15 fighter jets, an MQ‑9 Reaper combat drone, and multiple A‑10C Thunderbolt II attack aircraft deployed to Jordan’s Muwaffaq Salti Air Base, underscoring Washington’s effort to combine diplomatic pressure with a visible show of force. The buildup comes as the U.S. issues a stark advisory urging its citizens in Iran to leave immediately and prepare to depart without government assistance, ahead of sensitive talks focused on Tehran’s nuclear program.
