Regional Approach had just let us descend to 4000 ft on final to 13R. We were just about a mile west of MORRY fix when Approach cleared us for a visual approach. My FO was just starting to descend to 3000 ft when I noticed a TCAS target appear approximately 3 miles southeast of our position. It was below our altitude and roughly 500 ft below our current altitude of 3800 ft. I told my FO to stop the descent at which point as the target got close we received a Climb TCAS RA. At the same time approach then called a target to us and I told approach we were responding to a TCAS RA. The VFR Aircraft passed at our 12 position roughly 300 ft below us. Approach asked if we still had the runway in sight and we were cleared the visual approach and switched us to tower. Before leaving frequency I asked Approach if that was a VFR aircraft he declared yes; but didn't seem concerned! I still would like to know why or how this VFR aircraft was able to fly at that altitude inside our approach to 13R without anyone doing something. Regional Approach was swamped with the time of arrivals to DFW and very task saturated. However someone needs to research who the VFR pilot was and track them down and teach them DFW airspace restrictions.
At approximately 16 DME on the ILS 13R DFW; after we had been cleared the approach; and as I began to descend from 4000 ft to 3000 ft; we received a TCAS RA. The other aircraft was spotted visually at our 12:30 and approximately 1 mile. TCAS indicated that it was level; 400 ft below our altitude. It was headed due north; possibly along I-35W. As I began climbing in response to the TCAS RA; ATC called out the traffic to us; and the Captain replied that we had the traffic in sight and we were climbing in response to a TCAS RA. As soon as we were clear; I resumed the descent and finished flying the approach uneventfully.The weather was night VMC. We were configured with flaps 2 and all exterior lights on. Speed was approximately 170 KIAS.
A321 flight crew reported responding to an RA from VFR traffic transiting DFW airspace apparently without clearance.
