Sri lanka air force (SLAF) fighter jets carried out consecutive air strikes on LTTE's Vishwamadhu base yesterday (21st) and today (22nd). Initial bombing run was performed at 12.15pm yesterday and the base was hit again by SLAF bombers today at around 7.00 am. The second air strike targeted the LTTE cadres who were engaged in recovering usable items from areas targeted in the first raid. As with most air strikes, LTTE casualty details cannot be confirmed as of now.
Vishwamadhu base was frequently used by LTTE's Imran regiment. Several of their ammunition and fuel dumps were said to be located inside the base premises. UAV footage shows secondary explosions after the initial bombing run which suggest that at least one of the ammo or fuel dumps was hit.
Imran-Pandiyan is regarded as one of the most powerful fighting formations within the LTTE. This unit, along with Charles Anthony brigade, has not been used in any major battle since the 2002 CFA. The tigers seem to be keeping their two most experienced brigades in reserve. LTTE is most likely to use these brigades to defend Wanni from a possible army invasion but the possibility of these units being deployed in a major LTTE offensive to recapture Jaffna peninsula cannot be overruled either.
