During engine start First Officer introduced fuel at N2 20% and N1 rotation but no ITT (Inter Turbine Temperature) increase. He then mentioned this looks strange [to] which I replied looks like a hung start; let's go ahead and shutdown and motor the engine. A call came over the apron frequency; saying our engine was on fire. I said let's continue to motor; First Officer said hey we are already at 60 seconds. Just after the First Officer said that another call came in saying you guys are still on fire on the apron frequency. At that point the First Officer suggested we run the Emergency Damage/Engine Fire On The Ground checklist. We ran the checklist through the fire push then we got another [call] saying fire still coming from the engine and fuel on the ground. At that point we fired both bottles into the right engine. I told apron to call the fire trucks fearing the fire was not out and fuel on the ground and the safety of the passengers. Fire trucks came. I made my second announcement letting the passengers know the fire trucks were only taking a look to make sure we are good to return to the gate. Firefighters examined the engine and only noticed black smoke; no fire. They followed us to the gate under tow. After the event the Fireman said he thinks that firing our bottles was the best decision; and that was the end of his narrative. Dispatch was notified and Operations. Arrival announcement was made as normal. Passengers didn't seem shaken; were only concerned when they'll reach [destination] and when is the next flight.
