Liège began to suffer from a relative decline of its industry , particularly the coal industry , and later the steel industry , producing high levels of unemployment and stoking social tension . During the 1960-1961 Winter General Strike , disgruntled workers went on a rampage and severely damaged the central railway station Guillemins . The unrest was so intense that " army troops had to wade through caltrops , trees , concrete blocks , car and crane wrecks to advance . Streets were dug up . Liège saw the worst fighting on 6 January 1961 . In all , 75 people were injured during seven hours of street battles . " On 6 December 1985 , the city 's courthouse was heavily damaged and one person was killed in a bomb attack by a lawyer
