Three firefighters were injured during the event, as dozens of teams continued working with trucks and planes to control the fires as they spread northward towards Highway 1.
While being treated for smoke inhalation, the man admitted to intentionally starting the fire. He told authorities he had been held against his will since the age of 11.
The firefighters came down the building, donning Batman, Superman, and Spiderman costumes while the residents of the institutes cheered on.
The rider managed to extricate himself from the pit, but the horse remained stuck.
The fire is said to have started in a nearby factory, and residents reported a large cloud of smoke rising from the area.
The New York City Fire Department reported at the scene that the fire was "six feet by 40 feet long."
The Fire and Rescue Authority said its firefighters were at the scene and were monitoring the gas levels in the area as a result.
At least 30 rockets were fired toward northern Israel communities as far south as Karmiel.
Some of the projectiles were intercepted, while several others fell in the area of the Western Galilee.
Separately, seven firefighting teams were working to control fires that broke out in several open areas near Kibbutz Amiad.
