DUBAI, United Arab Emirates (AP) — The US Navy’s Mideast-based 5th Fleet is starting to offer rewards for information that could help sailors intercept weapons, drugs and other illicit shipments across the region amid tensions over Iran’s nuclear program and Tehran’s arming of Yemen’s Houthi rebels.

While avoiding directly mentioning Iran, the 5th Fleet’s decision to offer cash and other goods for actionable intelligence in the Persian Gulf and other strategic waterways may increase pressure on the flow of weapons to the Houthis as a shaky cease-fire still holds in Yemen.

Already, the Houthis have threatened a new allied task force organised by the 5th Fleet in the Red Sea, though there’s been no attack by the Iranian-backed forces on the Navy in the time since.

Meanwhile, the 5th Fleet says it and its partners seized $500 million in drugs alone in 2021 — more than the four prior years combined. The 5th Fleet also intercepted 9,000 weapons in the same period, three times the number seized in 2020.

“Any destabilizing activity has our attention,” Commander Timothy Hawkins, a 5th Fleet spokesman, told The Associated Press. “Definitely we have seen in the last year skyrocketing success in seizing both illegal narcotics and illicit weapons. This represents another step in our effort to enhance regional maritime security.”

The 5th Fleet’s new initiative launches on Tuesday through the Department of Defense Rewards Program, which saw troops offer cash and goods for tips on the battlefields in Afghanistan, Iraq and elsewhere after al-Qaida launched the September 11, 2001, attacks. Since ground fighting has largely halted across the region, the 5th Fleet decided to try to use the program as it patrols the waterways of the Middle East.

Hawkins said operators fluent in Arabic, English and Farsi would man a hotline, while the Navy also would take tips additionally online, in Dari and Pashto. Payouts can be as high as $100,000 or the equivalent in vehicles, boats or food for tips that also include information on planned attacks targeting Americans, Hawkins said.

The rewards program marks the latest initiative under 5th Fleet Vice Admiral Brad Cooper, who also launched a drone task force last year amid tensions with Iran.
