Aircraft
We were in cruise at FL320. The cabin called us to report fumes in the aft galley. The FA (Flight Attendant) reported that she had followed her procedure for such an event which included shutting down the galley and pulling the CB in the aft galley. I said call me back in a minute and let me know if it clears. She called back almost immediately and told me that the fumes were getting worst and that it smelled like burning plastic. My FO (First Officer) and I immediately donned our O2 masks and followed the procedure for 'Smoke.' I complied with the emergency procedure while the FO (PF; Pilot Flying) [notified ATC]. ZZZ was the closest suitable airport; so we requested an immediate descent and vectors for an approach into ZZZ. Late in the descent; the FA's reported that the fumes had diminished somewhat. We landed at ZZZ. ARFF (Airport Rescue and Fire Fighting) approached the aircraft and after checking the cargo holds; could not determine the source of the fumes.
I was the PF (Pilot Flying.) Approximately 30-40 miles west of ZZZ; during cruise; the Cabin Crew reported smoke/fumes in the aft galley. There were no ECAM indications regarding a smoke/fumes event taking place in the aircraft. The cabin crew in the front of the aircraft and mid cabin did not report seeing smoke or smelling fumes. FA (Flight Attendant) in the aft galley stated that she had pulled circuit breakers in the aft galley in an attempt to eliminate the smoke/fumes. However; she reported that she could still smell the fumes. Captain and I put on O2 and we decided to divert to ZZZ as it was the closest usable airport. The Captain told me that he would run the Smoke/Fumes checklist on the QRC. He asked me [to contact] with Center and let them know we were diverting to ZZZ. I [explained the situation to Center and] told them we were diverting to ZZZ due to smoke/fumes reported in the aircraft. I then asked for a heading to the airport. Told ATC that we would like the emergency vehicles standing by to meet us on the runway. ATC gave us a turn to the airport and cleared us to descend to 3;000 feet. During the descent the Captain communicated to the passengers that we were diverting due to a report of smoke/electrical fumes in the aft galley and that this was the safest course of action. He also continued to communicate with the cabin crew to confirm if the fumes were getting worse or not. They reported that the situation was not worsening. We continued the descent into ZZZ and landed safely. The emergency operators met us on the runway and were able to confirm that there was no smoke/fumes in any of the cargo holds. Once they had completed their inspection of the aircraft exterior we taxied to the gate.The cabin crew in the aft galley reported smoke/fumes in the aft galley; but could not determine its origin or exact location. Based off of that information we diverted to ZZZ. Since the only information that we had was a report by the cabin crew of the smoke/fumes we felt it was safest to land ASAP to avoid a potentially worsening situation.I don't know what we could have done to avoid this situation. Obviously a report from a FA of smoke/fumes in the galley is serious. Since they could not determine where it was coming from and since we had no ECAM indications to possibly provide us with some more information of the only safe choice to make was to land quickly. I feel that we had excellent communication between the flight deck and the cabin crews which enabled us to make a quick decision to divert. We were able to get the aircraft on the ground quickly and safely.
A321 flight crew reported divert due to Flight Attendant notification of smoke and fumes in the aft galley.
