Timeline of attacks on US forces as threats increase in Middle East

As tensions heighten in the Middle East, U.S. forces in the region are facing hostile threats and an array of attacks as the Biden administration increases its support for Israel. 

A U.S. naval warship shot down 15 drones and four cruise missiles Thursday during a nine-hour span near the Yemeni coast, a larger barrage than was previously thought.

The USS Carney, a guided missile destroyer, was heading south through the Suez Canal in Egypt on Wednesday and was in the northern Red Sea when incidents occurred on Thursday.

Since the war between Israel and Hamas began on Oct. 7, there have been a handful of attacks on U.S. positions in the Middle East. The Pentagon has moved warships and aircraft to the region to be ready to provide Israel with assistance.

In addition, 2,000 U.S. troops were put on heightened alert and are ready to be deployed if needed. The troops are likely Army and Air Force personnel and would be able to respond quickly, particularly to provide intelligence and surveillance, transportation and medical assistance.

The aggression against American military personnel coincides with protests and riots near U.S. embassies in the Middle East. Below is a rundown of attacks on U.S. forces in recent days. 

U.S. forces intercepted two one-way attack drones targeting Iraq's al-Asad air base just west of Baghdad where American troops are located. One drone was destroyed, and the other was damaged, U.S. Central Command said. 

Coalition forces sustained minor injuries and there was some damage to the base. 

In another part of Iraq, U.S. forces at the al-Harir air base destroyed a drone. No injuries were reported. 

"Our missiles, drones, and special forces are ready to direct qualitative strikes at the American enemy in its bases and disrupt its interests if it intervenes in this battle," Ahmad "Abu Hussein" al-Hamidawi, head of the Iraqi Kataib Hezbollah militia, said in a statement. 

The USS Carney was in the Northern Red Sea when it shot down the four cruise missiles and 15 drones launched by Iran-backed Houthi rebels in Yemen. No injuries or damage were reported. 

The Defense Department initially said the warship shot down three land attack cruise missiles and "several" drones before the full scale of the attack was known. 

A defense official said the cruise missiles and drones were shot down with the SM-2 surface-to-air missiles and that the rockets were clearly headed for Israel. A U.S. official said they don't believe the missiles — which were shot down over the water — were aimed at the U.S. warship.

On the same day, the Al Tanf Garrison military base in southern Syria where American troops are present was targeted by two drones. U.S. and coalition forces engaged and destroyed one drone while the other impacted the base. 

U.S. troops have maintained a presence at the base for a number of years to train Syrian allies and monitor Islamic State militant activity.

Two rockets were fired toward the Baghdad Diplomatic Support Center in Iraq, near the Baghdad International Airport around 2:50 a.m. 

One rocket was intercepted by a counter-rocket system and the other impacted an empty storage facility. No casualties were reported.
