Eelam War IV 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 ( see list ) . Renewed hostilities began on the 26 July 2006 , when Sri Lanka Air Force fighter jet s 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 field s in the area . The fighting resumed after a four - year ceasefire between the Government of Sri Lanka ( GoSL ) and LTTE . Continued fighting led to several territorial gains for the Sri Lankan Army , including the capture of Sampur , Vakarai and other parts of the east . The war took on an added dimension when the LTTE Air Tigers bombed Katunayake airbase on March 26 , 2007 , the first rebel air attack without external assistance in history . Eelaam War IV ended on 18 May 2009 with the Sri Lanka Army gaining control of the last bit of territory held by the LTTE and with the death of the LTTE leader Velupillai Prabhakaran . The final few days of the war near Nandikadal Lagoon in the north east of the island saw very heavy fighting and led to Sri Lankan forces being accused of war crimes , which were denied by the government . Some 300 , 000 Tamil civilians who were trapped inside the war zone and prevented from escaping by the LTTE were caught in the crossfire during the final phase of the war . Peace process 2002 . The elections , held on 5 December 2001 saw a sweeping victory for the United National Front , led by Ranil Wickremasinghe , who campaigned on a pro - peace platform and pledged to find a negotiated settlement to the conflict . On 19 December , amidst efforts by Norway to bring the government and the Tamil Tigers to the negotiating table , the LTTE announced a 30 day ceasefire with the Sri Lankan government and pledged to halt all attacks against government forces . The new government welcomed the move , and reciprocated it 2 days later , announcing a month long ceasefire and agreeing to lift a long standing economic embargo on rebel - held territory . Signing of MoU . The two sides formalized a Memorandum of Understanding ( MoU ) on February 22 , 2002 and signed a permanent ceasefire agreement ( CFA ) . Norway was named mediator , and it was decided that they , together with the other Nordic countries , monitor the ceasefire through a committee of experts named the Sri Lanka Monitoring Mission . In August , the government agreed to lift the ban on the LTTE and paved the way for the resumption of direct negotiations with the LTTE . Following the signing of the ceasefire agreement , commercial air flights to Jaffna began and the LTTE opened the key A9 highway , which linked government controlled area in the south with Jaffna and ran through LTTE territory , allowing civilian traffic through the Vanni region for the first time in many years . Many foreign countries also offered substantial financial support if peace was achieved and optimism grew that an end to the decades long conflict was in sight . The much anticipated peace talks began in Sattahip Naval Base , Chonburi Province , Thailand on the September 16 and 5 further rounds followed in Rose Garden , Nakhorn Pathom Province , Norway and Berlin , Germany . During the talks , both sides agreed to the principle of a federal solution and the Tigers dropped their long standing demand for separate state . This was a key compromise from the LTTE , which had always insisted on an independent Tamil state and it also represented a compromise from the government , which had seldom agreed to more than minimal devolution . Both sides also exchanged prisoners of war for first time . Beginning of the war . A new crisis leading to the first large - scale fighting since signing of the ceasefire occurred when the LTTE closed the sluice gate s of the Mavil Aru reservoir on July 21 and cut the water supply to 15 , 000 villages in government controlled areas . After initial negotiations and efforts by the SLMM to open the gates failed , the Air Force attacked LTTE positions on July 26 , and ground troops began an operation to open the gate . Palitha Kohona , a government spokesman , stated that the government remained committed to the cease - fire . Likewise , the LTTE also claimed that they were committed to the ceasefire The sluice gates were eventually reopened on August 8 , with conflicting reports as to who actually opened them . Initially , the SLMM claimed that they managed to persuade the LTTE to lift the waterway blockade conditionally . However a government spokesman said that " utilities could not be used as bargaining tools " by the rebels and government forces launched fresh attacks on LTTE positions around the reservoir . These attacks prompted condemnation from SLMM Chief of Staff , who stated " ( The government ) have the information that the LTTE has made this offer . " " It is quite obvious they are not interested in water . They are interested in something else . " The LTTE then claimed they opened the sluice gates " on humanitarian grounds " . Eventually , following heavy fighting with the rebels , government troops gained full control of the Mavil Aru reservoir on August 15 . War in east . The war between LTTE and Sri Lankan government started after the failure of Norway brokered cease fire on July 21 , 2006 , when LTTE cut off the water supply to the rice growing fields in the Mavil aru area in eastern Trincomalee district . The government military claimed the total control of the eastern province after capturing the Thoppigala ( Baron ' s cap ) on July 11 , 2007 nearly a year of fighting . The TMVP contested Batticaloa district local council election on March 10 , 2008 and won all 9 councils with a high majority 70 % of votes . The party also contested in Eastern Provincial Council election May 10 , 2008 under the ruling UPFA banner and UPFA won the election .

Karuna has also been accused of gross human rights violations such as forming death squads , harassing journalists , extrajudicial killings , abductions , and the use of child soldiers against the LTTE . Apart from that his group has split due to alleged financial corruption issues . Karuna , with the help of the Government of Sri Lanka , was smuggled into Great Britain for refuge . He was later arrested by British authorities for illegal entry and is being probed for war crimes . Sri Lanka pulls out of ceasefire . On January 2 , 2008 , The Sri Lankan government unanimously decided to formally withdraw from the ceasefire with the separatist Tamil Tiger rebels , which had existed only on paper over the past two years . Prime Minister Ratnasiri Wickramanayake had proposed that the cabinet annul the truce after yet another bomb blast went off on January 2 in the capital , Colombo , killing five and injuring over 28 . " The Government of Sri Lanka yesterday ( 3rd January 2008 ) formally notified the Norwegian Government of its decision to terminate the Agreement on a “ Ceasefire ( CFA ) between the Government of the Democratic Socialist Republic of Sri Lanka and the Liberation Tigers of Tamil Eelam ” concluded on 22nd February 2002 .

Initially , the Tigers broke through army defense lines around Muhamalai , and advanced further north , but they were halted after 10 hours of fierce fighting . Isolated battles continued over the next few days , but the LTTE was forced to give up its offensive due to heavy casualties . Sporadic fighting in the North has been going on for months , but the intensity of the clashes has increased since September 2007 . During clashes in the Forward Defence Lines , separating their forces , both sides exchange heavy artillery fire , after which military incursions follow .

The security forces were unable to bring down the aircraft prompting much criticism from the public and opposition political parties .
