IRAs South Armagh brigade kill 9 RUC officers in a mortar attack at Newry RUC station, 1985.

The attack was jointly planned by members of the South Armagh Brigade and an IRA unit in Newry.The homemade mortar launcher, dubbed the 'Mark 10', was bolted on to the back of a Ford lorry that had been hijacked in Crossmaglen. Shortly after 6.30 pm on 28 February, nine shells were launched from the lorry, which had been parked on Monaghan Street,about 250 yards (230 m) from the base.At least one 50 lb (23 kg) shell landed on a portacabin containing a canteen, where many officers were having their evening tea break. Nine police officers were killed and 37 people were hurt, including 25 civilian police employees; the highest death toll inflicted on the RUC in its history.The nine dead officers ranged in age from 19 to 41, seven male and two female, seven Protestants and two Catholics.Another shell hit the observation tower, while the rest landed inside and outside the perimeter of the base The day was dubbed"Bloody Thursday" by the British press. British prime minister Margaret Thatcher called the attack "barbaric", while the Republic of Ireland's Taoiseach, Garret FitzGerald, said it was "cruel and cynical", and pledged the help of the Irish security forces to catch those responsible. Although not involved in the attack, Newry IRA member Eamon Collins was arrested shortly afterwards and interrogated. After five days of questioning, Collins broke under interrogation and turned supergrass, leading to more than a dozen arrests of other IRA members.The attack prompted calls from unionist politicians to "increase security", and the British government launched a multi-million pound programme of construction to protect bases from similar attacks. This involved installing reinforced roofs and building blast-deflecting walls around the base of buildings. After the successful attack in Newry, the IRA carried out a further nine mortar attacks in 1985. On 4 September, an RUC training centre in Enniskillen was attacked; 30 cadets narrowly escaped death due to poor intelligence-gathering by the IRA unit responsible. The cadets were expected to be in bed sleeping, but were instead eating breakfast when the bombs landed. In November 1986, the IRA launched another attack on the RUC base in Newry, but the bombs fell short of their target and landed on houses. A four-year-old Catholic girl was badly wounded and another 38 people were hurt, prompting the IRA to admit that "this incident left us open to justified criticism". Beginning in the 1990s, operations at the Corry Square base were progressively shifted to a new facility on the outskirts of Newry.The base was closed in 2002,
