Which country's longest continuous deployment began because of intense political and sectarian rioting in Northern Ireland?
1969 Northern Ireland riots During 12–17 August 1969, intense political and sectarian rioting took place in Northern Ireland. There had been sporadic violence throughout the year arising from the civil rights campaign, which was demanding an end to discrimination against Irish Catholics. Civil rights marches were repeatedly attacked by both Ulster Protestant loyalists and by the Royal Ulster Constabulary (RUC), a unionist and largely Protestant police force.
Nagorno-Karabakh line of contact The Nagorno-Karabakh line of contact (Armenian: շփման գիծ , "shp’man gits", Azerbaijani: "təmas xətti" ) is a militarized area that separates the Armenian forces (namely the Nagorno-Karabakh Defense Army) and the Azerbaijan Armed Forces. It was formed in the aftermath of the May 1994 ceasefire that ended the Nagorno-Karabakh War (1988–94). It has been described as "heavily fortified," "a heavily-mined no-man's-land," and a "buffer zone of trenches." According to Thomas de Waal it is the "most militarised zone in the wider Europe," and one of the three most militarized zones in the world (along with Kashmir and North Korea). De Waal described it as a "fearsome scar on the map, more than 200 km long, with World-War-I-style trenches on either side, bristling with heavy weaponry." Gerard Toal and John O'Loughlin wrote in the "Washington Post" that the line of contact "features World War I-style trenches on both sides, in some places three rows deep."
