Aircraft
I was the flying pilot on a positioning leg to ZZZZ. While on a southerly heading and climbing through 26;400 feet MSL the red RIGHT ENGINE FIRE master caution light illuminated. Upon seeing the light and hearing the accompanying warning klaxon; monitoring pilot and myself performed the memory items associated with an engine fire. We next notified ATC that we had shut down an engine and would need to divert to ZZZ; the nearest suitable airport. After verifying with ATC that the reported weather at ZZZ was above the published minimums for the ILS approach; we requested that ATC give us vectors onto the localizer.As the Quick Reference Handbook was on my side of the cockpit at the time of the event; I transferred control of the aircraft to [the] Captain and performed the ENGINE DAMAGE/FIRE DURING FLIGHT and SINGLE ENGINE APPROACH AND LANDING checklist procedures. After several vectoring turns from ATC to allow us to lose altitude and avoid areas of heavy precipitation; we were vectored onto the localizer and flew the ILS and landed. After shutdown; I performed a post-flight inspection and was unable to find any evidence of damage to the right engine. Event occurred while we were momentarily in the clear after exiting a heavy line of precipitation.From a flight-crew standpoint; the incident appears to be unavoidable.
CL604 First Officer reported experiencing a right engine fire master caution warning light and associated audible klaxon. They accomplished the appropriate checklist items; shutdown the engine; and safely diverted to the nearest suitable airport. No damage was found while inspecting the engine post flight.
