Narrative:

Following an uneventful take off; cruise; and initial descent; we received a 'fire' indication for the left engine on the warning panel. I continued to fly the plane and now took the radios; while the captain ran the emergency checklist. We declared an emergency and asked for the nearest suitable airport with a long runway; and fire fighting capabilities. ATC informed us that ZZZ was 22 miles straight ahead with favorable wind and weather conditions; so we proceeded. The engine was shut down and secured as per the checklist. With the fire indication persisting; the captain pressed the 'fire ext' button; which didn't seem to have an effect; the 'fire' indication and the 'fire ext' button continued to flash. I landed visually; and then stopped on the runway. The fire department met us on the runway and inspected the engine for any indication of fire. No indication was found. We then single engine taxied to the ramp; where we met with base personnel and cleared customs.
