The Pentagon on Thursday confirmed the 28th attack on U.S. forces in Iraq and Syria since October 17. 

A U.S. Department of Defense official confirmed to Fox News that one drone struck the al-Tanf U.S. military base in Homs Governorate, Syria, but said there was no damage to U.S. facilities or personnel. 

The Iraqi pro-militia outlet Sabereen had said two drones targeted the base, but the DoD official said it was only one drone that struck. The incident represented the 28th attack on U.S. forces in Iraq and Syria since October 17 and the seventh since the U.S. airstrikes Thursday night. 

An Iraqi government source had also told Reuters two drones targeting Syria's al-Tanf region were disabled or destroyed by the base defense system Wednesday.

The thwarted attack comes as U.S. and Coalition Forces at Combined Joint Task Force Operation Inherent Resolve (CJTF-OIR) installations in Iraq and Syria have been attacked at least 27 times between Oct. 17-31.

Of these attacks, 16 happened in Iraq and 11 took place in Syria. They included a mix of one-way attack drones and rockets.

Most of these attacks were successfully disrupted by military forces and most failed to reach their targets, thanks to robust defenses. One U.S. contractor died as a result of cardiac arrest, when warned of an attack. Several other injuries were reported.

Four total attacks took place in both countries on October 30.

A multi-rocket attack occurred against U.S. and coalition forces at Al-Asad Airbase, Iraq. Earlier in the day, multiple one-way attack drones were shot down at the same base. There were no casualties or damage to infrastructure reported for either attack.

On Oct. 19, the Al-Asad Air Base, Iraq was attacked again, as was the Baghdad Diplomatic Support Center in Iraq, which houses U.S. and coalition personnel.

That same day, a rocket struck the Mission Support Site Euphrates in Syria.

The Al-Asad Airbase was attacked once on Oct. 18 and once on Oct 17. During the attack on the 17th, a number of personnel sustained minor injuries. The civilian contractor, a US national, also died. One hangar with a small aircraft inside was also destroyed.

The attacks stemmed from violence between Israel and Hamas in Gaza, as the U.S. has backed the Middle Eastern democracy in its war against terror.

Defense officials have said Iranian-forces are believed to have backed the attacks.

Senior U.S. officials, including President Biden, Vice President Harris and Secretary of State Antony Blinken have discouraged Iran from getting involved. They have also vowed retaliation if U.S. forces are intentionally targeted but have not specified which actions they would take.

The U.S. has deployed carrier group and other forces in the Mediterranean Sea and sent an additional 300 more troops on Wednesday.
