One of the four Americans killed in a suicide bomb attack in Syria this week was a Navy sailor and married mother of two whose father is a high-ranking officer in the New York State Police, officials said Friday.

The attack targeted US-led coalition forces in the northern Syrian city of Manbij on Wednesday. Manbij has been held by US-backed fighters allied to the Kurdish YPG militia since they took it from ISIS in 2016. It is located near areas held by Russian-backed Syrian government forces and by anti-Assad fighters backed by Turkey.

The Pentagon identified three of the four Americans killed in Wednesday’s attack in the northern Syrian town of Manbij.

They are Army Chief Warrant Officer 2 Jonathan R. Farmer, 37, of Boynton Beach, Florida, who was based at Fort Campbell, Kentucky; Navy Chief Cryptologic Technician (Interpretive) Shannon M. Kent, 35, of Pine Plains, New York, and based at Fort Meade, Maryland; and a civilian, Scott A. Wirtz, from St. Louis.

The Pentagon hasn’t identified the fourth casualty, a civilian contractor.

The attack, claimed by ISIS, also wounded three US troops and was the deadliest assault on US troops in Syria since American forces went into the country in 2015.

The Pentagon’s statement said Kent was from upstate New York but didn’t give a hometown. New York Gov. Andrew Cuomo said in a statement Friday that she was from Pine Plains and was the daughter of state police field commander Col. Stephen Smith, the agency’s third-highest position.

“We owe her our eternal gratitude for her selfless dedication and sacrifice,” Cuomo said while ordering flags on state government buildings to be flown at half-staff in Kent’s honor.
