Eelam War IV is the name given to the fourth phase of armed conflict between the Sri Lankan military and the separatist Liberation Tigers of Tamil Eelam (LTTE), which is currently proscribed as a terrorist organisation by 32 countries. Renewed hostilities began on the 26 July 2006, when Sri Lanka Air Force fighter jets bombed several LTTE camps around Mavil Aru anicut. The government's casus belli was that the LTTE had cut off the water supply to surrounding paddy fields in the area.
