totalling little more than 3% of the island. The same year the Turkish parliament voted in favour of the intervention of Cyprus but the lack of support that Turkey faced from both the UN and NATO prevented it. In answer Grivas was recalled to Athens and the Greek military force left the island. In 1967, on Cyprus Airways Flight 284 a de Havilland Comet suffered an explosion in the cabin, killing 66. The cause and motive were unsolved, but a recovered seat cushion showed traces of a military plastic explosive. Following another outbreak of inter communal violence in 1967–68, a Turkish Cypriot provisional administration was formed. Greek coup d'état and Turkish invasion In July 1974, the President was overthrown by the 1974 Cypriot coup d'état carried out by Greece, which was under Greek military junta rule.

In a two-stage offensive, Turkish troops took control of 38% of the island and 200,000 Greek Cypriots fled the northern areas which were under occupation, whilst at the same time 60,000 Turkish Cypriots were transferred to these northern occupied areas by the United Nations and British SBA authorities after an agreed temporary population exchange by Turkish and Greek leaders. Since then, the southern part of the country has been under the control of the internationally recognized government of Cyprus and the northern part under the control of the government of Northern Cyprus. Present day In 1983, the 1974 Turkish Cypriot-controlled area declared itself as the Turkish Republic of Northern Cyprus, recognised only by Turkey. United Nations Peacekeeping Forces maintain a buffer zone between the two sides. Except for occasional demonstrations or infrequent incidents between soldiers in the buffer zone, there was no violent conflict from 1974 until August 1996, when Anastasios (Tassos) Isaac and Solomos Solomou were killed while demonstrating in a motorcycle rally after crossing into the Turkish Republic of Northern Cyprus area. Tassos Isaak was beaten to death by a group of Turkish civilians and three Turkish Cypriot policemen. Solomos Solomou was shot in the throat by a Turkish army officer when he
