In July 1982, the IRA bombed military ceremonies in London's Hyde Park and Regent's Park, killing four soldiers, seven bandsmen, and seven horses. The INLA was highly active in the early and mid-1980s. In December 1982, it bombed a disco in Ballykelly, County Londonderry frequented by off-duty British soldiers which killed 11 soldiers and six civilians. In December 1983, the IRA attacked Harrods using a car bomb, killing six people. One of the IRA's most high-profile actions in this period was the Brighton hotel bombing on 12 October 1984, when it set off a 100-pound time bomb in the Grand Brighton Hotel in Brighton, where politicians including Thatcher were staying for the Conservative Party conference. The bomb, which exploded in the early hours of the morning, killed five people, including Conservative MP Sir Anthony Berry, and injured 34 others.
