The U.S. is beefing up its use of fighter jets around the strategic Strait of Hormuz to protect ships from Iranian seizures, a senior defense official said Friday, adding that the U.S. is increasingly concerned about the growing ties between Iran, Russia and Syria across the Middle East.
Speaking to Pentagon reporters, the official said the U.S. will send F-16 fighter jets to the Gulf region this weekend to augment the A-10 attack aircraft that have been patrolling there for more than a week. The move comes after Iran tried to seize two oil tankers near the strait last week, opening fire on one of them.
Black Sea. The incident spiked tensions between the two countries and triggered a call between their defense chiefs, but led to no direct military response.
Last week, Rear Adm. Oleg Gurinov, head of the Russian Reconciliation Center for Syria, said the Russian and Syrian militaries have been doing joint training. In comments carried by Syrian state media, he said Moscow is concerned about drone flights by the U.S.-led coalition over northern Syria, calling them “systematic violations of protocols” designed to avoid clashes between the two militaries.
U.S. and Russian military commanders routinely communicate over a deconfliction phone line that has been in place for several years to avoid unintended clashes in Syria, where both sides have troops on the ground and in the air.
There are often many calls a day, and at times result in angry threats as commanders argue over an ongoing operation, said the U.S. official. Describing a conversation, the official said the Russians will often declare an area of space a restricted operating zone and say they are doing military exercises there.
The U.S. sees no exercises, and tells Russia that American forces are on a counterterror mission against the Islamic State group and plan to fly in that area. The Russians then say they can’t guarantee U.S. aircraft safety if they go there. And once the mission begins, and the aircraft move into the zone, “it sometimes gets very heated,” said the official, as both sides loudly protest and reject the other’s assertions.
The most recent incident was Friday morning, when a Russia aircraft flew repeatedly over the at-Tanf garrison in eastern Syria, where U.S. forces are training Syrian allies and monitoring Islamic State militant activity. The official said the Russian An-30 aircraft was collecting intelligence on the base.
The U.S. did not have fighter aircraft in the area and took no direct action against the Russian flight.
