Narrative:

While at 24000 ft on arrival, ATC issued an immediate right turn and climb to 25000 ft to avoid traffic. At rollout TCASII issued a TA and we verified a TCASII target at 12 O'clock and approximately 5 mi 500 ft above. Then ATC issued a left turn and an immediate descent to 24000 ft. At the same time, we received the RA on the 12 O'clock traffic. We followed RA and avoided any further conflict. Supplemental information from acn 319114: at FL250 ATC issued a left turn and immediate descent to FL240. At the same time, we received a TCASII RA.
