Narrative:

During the takeoff roll; at 60 KTS; the right engine began to surge and the aircraft began to pull hard towards the right with severe vibrations emitting from nose gear. As a result; a rejected takeoff was immediately accomplished. Once stopped on the runway; the purser notified the flight deck that; just prior to the rejected takeoff; fas (flight attendants) and passengers witnessed flames emitting from the exhaust section of the right engine. Tower was notified; fire rescue requested; passengers told to remain seated; and all required checklists completed. The right engine was manually shutdown. Fire rescue visually inspected the right engine and notified flight deck of no visible damage or fire. A return to the gate was requested along with a fire rescue escort. Just prior to gate arrival; fire rescue gave all clear and safe to continue. Aircraft stopped prior to turning into the gate and remaining engine was shutdown and the aircraft was towed into the gate.
