Officials in central Florida say the cost of responding to last month's Pulse nightclub shooting by police officers, firefighters, hazmat crews and others comes to more than $1.7 million.

Figures released Tuesday by the city of Orlando show the city's expenses at under $600,000, with almost two-thirds of the costs from overtime outlays.

More than a dozen other central Florida agencies spent a combined $1.1 million. The cost to Orlando Regional Medical Center, where most victims were treated, was $632,000.

The U.S. Department of Justice has made $1 million available to help reimburse agencies for the costs of responding to the Pulse massacre.

Gunman Omar Mateen opened fire at Pulse on June 12, killing 49 patrons and injuring 53 people. He was killed in a shootout with police.
