Narrative:

I climbed air carrier X (A319) to miss another aircraft, but climbed him into another aircraft. The conflict alert activated before I saw it. Supplemental information from acn 508477: at FL310, we were issued an immediate left turn to heading 360 degrees approximately 90 degrees from our jetway. While in turn, we noticed a TCASII target at our 6 O'clock position at the same FL310. No TCASII TA's or RA's were commanded. Once separation was regained we were cleared on course. We requested a verbal explanation and none was given!
