I cleared Aircraft Y for takeoff on Runway 24L. Aircraft X was rolling out on Runway 24R. I took care of other things; and next thing I observed was Aircraft X about to cross the runway while Aircraft Y was rolling one third down the runway. I yelled out 'Aircraft X stop' 'Aircraft X hold' then I instructed Aircraft Y to abort and cancel take off clearance. I did not cross Aircraft X; I had not expected Aircraft X to cross the runway. I expected all aircraft to hold short of the parallel runway; since there is enough space to clear the runway they just landed.Aircraft Y had to sit on the runway for about 10 minutes to check his aircraft (with help of rescue department) and taxied off the runway on his own. We need the center taxiway between Runway 24L and Runway 24R. Better educate foreign pilots to what they can and cannot do after landing.
Cleared for takeoff 24L E8 shortened. As we taxied onto runway; an aircraft was rolling out on 24R. We began the takeoff roll as the aircraft was exiting onto AA. After 80 kt callout the CA questioned whether the aircraft was stopping short of 24L. We both noted that the aircraft was not stopping and the Captain called to abort the takeoff at approximately 110 kts. Immediately thereafter; tower told the crossing aircraft to 'stop; stop' and called for us to abort the takeoff. The traffic had not received a clearance to cross 24L but failed to hold short of the runway. After the rejected takeoff; we remained on the runway until ARFF inspected [us] for damage. No damage noted. Returned to gate for further inspection by maintenance.
LAX Tower Controller reported of a runway incursion involving a foreign carrier. Controller had cleared an aircraft for departure while landing foreign carrier was rolling out on parallel runway. Aircraft did not stop on taxiway between the runways. Controller advised aircraft to stop. Controller told departing aircraft to abort and cancel takeoff clearance.
