The defence ministry quoting the Sri Lanka Air Force said raids were carried out with "pinpoint accuracy on information obtained through real-time air surveillance and ground reconnaissance."
The defence ministry said the location had been visited by a "high profile LTTE terrorist".
Sri Lanka jets bombed a complex killing Tamil Tiger political wing leader S P Tamilselvan last year, and reports said another bombing raid had hit a bunker injuring Tiger leader Velluppillai Prabhakharan.
