Liverpool have condemned the recent "vile" chants about the Hillsborough disaster.
Manchester City supporters were heard singing during a minute's silence to mark the 33rd anniversary of the tragedy, held ahead of Liverpool's 3-2 win in their FA Cup semi-final on Saturday afternoon. Manchester United fans were then heard making offensive chants at Anfield on Tuesday evening. Both Manchester clubs have since apologised.
97 Liverpool fans lost their lives as a result of the crush, which unfolded in the build-up to the team's FA Cup semi-final against Nottingham Forest in April 1989. The fixture was held at Sheffield Wednesday's Hillsborough Stadium in South Yorkshire.
