First, let us know why the sanctions were imposed. On 21 December 1989 bombed Pan Am flight 103 killing everyone on board. Britain and the UN accused two Libyan nationals of involvement, they were Abdel Basset al-Megrahi and Al-Amin Khalifa. The Libyan government refused to hand them over to the UN and the sanctions were imposed.
The first sanction was placed on 31 March 1992.
Resolution 748 An embargo was put on arms and air and the number of Libyan diplomatic personnel serving abroad were reduced. The member states were asked to carry out the directives.
