Peace talks in October have failed to bring an end to a 23-year civil war in Sri Lanka that has now claimed over 65,000 lives. Here are the main events in the conflict.
The LTTE was formed in 1976
1948 Ceylon gains independence from British rule dating back to the end of the 18th century.
The population is comprised of a Sinhalese majority that can be traced back to the sixth century BC and a Tamil minority, mainly concentrated in the north of the country, who have roots reachnig back to the third century.
1956 Sinhalese is made the only official language in a series of Sinhalese nationalist measures introduced by the government.
1958 Riots erupt between the Sinhalese and Tamil communities that leave many people dead and force several thousand people, mainly Tamils, to relocate to the north.
1972 Ceylon is renamed Sri Lanka.
The Tamil New Movement is formed by Velupillai Prabhakaran, made up mainly of university students calling for greater equality in the grading system and more places in higher education. In 1975 they assassinate the mayor of Jaffna, marking the emergence of violence in the Tamil campaign.
1976 The Liberation Tigers of Tamil Eelam (LTTE) are formed from the Tamil New Movement and other student groups.
The concept for a separate Tamil state (Tamil Eelam) to be established in the north of the country is first proposed by the Tamil United Liberation Front (TULF).
1977 The TULF, a coalition of small parties, wins the majority of seats in Tamil areas in the country's elections, but the government later bans them from parliament for advocating an independent state.
Both sides have sustained heavy losses
More riots break out following an alleged assault by Tamils on Sinhalese policemen.
1983 Ethnic tensions in the country erupt into the start of a civil war when 13 soldiers are killed in an LTTE attack. The raid triggers anti-Tamil riots in Colombo and other parts of the country that leave thousands of people dead and force Tamils to leave Sinhalese majority areas.
1985 The first attempt at peace talks between the two sides fails.
1987 Government soldiers push LTTE fighters back to the northern city of Jaffna.
In the same year the LTTE carries out what is believed to be its first suicide bomb attack when a lorry is driven into an army camp and explodes, killing 40 soldiers.
The government signs the Indo-Sri Lanka peace accords that makes several concessions to the Tamil fighters, including recognising Tamil as an official language. India agrees to help keep order in the north and east of the country via a peace-keeping force and agrees to stop helping Tamil fighters.
1988 Indian troops leave the country as violence escalates between the warring parties.
1991 The former Indian prime minister, Rajiv Gandhi is assassinated by a suicide bomber who is believed to be a member of the LTTE.
One of the war's fiercest battles takes place at the Elephant Pass army base that controls access to the Jaffna peninsula. Thousands of LTTE fighters surround the base and lay siege to it for a month in a battle that leaves around 2,000 dead on both sides.

March The LTTE begins to fracture when a Tiger commander, General Karuna, pulls 5,000 fighters out of the LTTE saying insufficient resources are being given to Tamils in the east of the country.
April General elections are held early and the party of president Kumaratunga is unable to secure an overall majority in parliament. Mahinda Rajapakse becomes prime minister.
December More than 30,000 Sri Lankans are killed and tens of thousands left homeless by the Indian Ocean Tsunami. Arguments ensue almost immediately about whether the large amount of international aid is sent to mainly Tamil or Sinhalese areas.
July A deal is reached to distribute around $3bn in aid among Tamils, Sinhalese and Muslims but the Sinhalese nationalist JVP party pulls out of the governing coalition in protest.
Rajapakse's presidency has seen an increase in violence
August The foreign minister, Lakshaman Kadirgamar, an ethnic Tamil and staunch critic of the LTTE, is killed by a sniper.
