Narrative:

We de-iced and ran all applicable checklists before takeoff. We had the wing and cowl anti-ice on for takeoff. During takeoff roll at approximately 60-70 KTS; we received both left and right wing anti-ice cautions messages followed by ice caution message. We rejected the takeoff; taxi cleared of runway and ran the rejected takeoff checklist. We then conferred with maintenance and returned to the gate. Mechanics did not know why it happened.
