A U.S. official has characterized a recent military operation in Syria as a “large-scale” offensive, targeting 70 sites across central regions known for harboring ISIS infrastructure and weaponry.

Another official, who remained unnamed due to the sensitive nature of the operations, indicated that additional strikes are anticipated in the near future.

In a bold statement, President Trump issued a stern warning to ISIS, cautioning them against any further attacks on American personnel.

“All terrorists who are evil enough to attack Americans are hereby warned — YOU WILL BE HIT HARDER THAN YOU HAVE EVER BEEN HIT BEFORE IF YOU, IN ANY WAY, ATTACK OR THREATEN THE U.S.A.,” the President declared emphatically.

The operation was executed with a formidable array of military assets. U.S. forces deployed F-15 Eagle jets, A-10 Thunderbolt ground attack aircraft, and AH-64 Apache helicopters, according to officials. Additionally, F-16 fighter jets from Jordan and HIMARS rocket artillery were utilized, as confirmed by one of the officials.

A-10 Thunderbolt ground attack aircraft and AH-64 Apache helicopters, the U S officials said. F-16 fighter jets from Jordan and HIMARS rocket artillery also were used, one official added.

US Central Command, which oversees the region, said in a social media post that American jets, helicopters and artillery employed more than 100 precision munitions on Syrian targets.

The attack was a major test for the warming ties between the United States and Syria since the ouster of autocratic leader Bashar Assad a year ago.

Trump has stressed that Syria was fighting alongside US troops and said al-Sharaa was “extremely angry and disturbed by this attack,” which came as the US military is expanding its cooperation with Syrian security forces.

Syria’s foreign ministry in a statement on X following the launch of US strikes said that last week’s attack “underscores the urgent necessity of strengthening international cooperation to combat terrorism in all its forms” and that Syria is committed “to fighting ISIS and ensuring that it has no safe havens on Syrian territory and will continue to intensify military operations against it wherever it poses a threat.”

Syrian state television reported that the US strikes hit targets in rural areas of Deir ez-Zor and Raqqa provinces and in the Jabal al-Amour area near the historic city of Palmyra. It said they targeted “weapons storage sites and headquarters used by ISIS as launching points for its operations in the region.”

IS has not said it carried out the attack on the US service members, but the group has claimed responsibility for two attacks on Syrian security forces since, one of which killed four Syrian soldiers in Idlib province.

The group in its statements described al-Sharaa’s government and army as “apostates.” While al-Sharaa once led a group affiliated with al-Qaida, he has had a long-running enmity with IS.

The Americans who were killed

Trump this week met privately with the families of the slain Americans at Dover Air Force Base in Delaware before he joined top military officials and other dignitaries on the tarmac for the dignified transfer, a solemn and largely silent ritual honoring US service members killed in action.

The guardsmen killed in Syria last Saturday were Sgt. Edgar Brian Torres-Tovar, 25, of Des Moines, and Sgt. William Nathaniel Howard, 29, of Marshalltown. Ayad Mansoor Sakat, of Macomb, Michigan, a US civilian working as an interpreter, also was killed.

The shooting near Palmyra also wounded three other US troops as well as members of Syria’s security forces, and the gunman was killed.

The assailant had joined Syria’s internal security forces as a base security guard two months ago and recently was reassigned because of suspicions that he might be affiliated with IS, Interior Ministry spokesperson Nour al-Din al-Baba has said.

The man stormed a meeting between US and Syrian security officials who were having lunch together and opened fire after clashing with Syrian guards.
