Here's a Wiki synopsis of 687:

United Nations Security Council Resolution 687 which was on 3 April 1991 set the terms with which Iraq was to comply after losing the Gulf War.
It required the destruction of all chemical, nuclear and biological weapons, as well as all ballistic missiles with range greater than 150km. These actions "represented steps towards the goal of establishing in the Middle East a zone free from weapons of mass destruction and all missiles for their delivery and the objective of a global ban on chemical weapons"(paragraph 14)
The resolution also required Iraq to honour all its international debts and pay war reparations to Kuwait.
The rest of the resolution reiterated the Iraq sanctions regime begun in UN Security Council Resolution 661, and laid the groundwork for the Oil-for-Food Programme by taking charge of the petroleum exports (paragraph 19).
The resolution was passed by 12 votes to one (Cuba) with two abstentions (Ecuador and Yemen) after a very extended meeting.[1]
