by sending aid to help the refugees

Explanation:

in order to help those people, UN security councils established The United Nations Assistance Mission for Rwanda (UNAMIR) in 1993 which is aimed to provide humanitarian assistance and helped defuse the situation In Rwanda.

But, UNAMIR was considered as a failure.

They failed to defuse the situation and provide the help that they intended to give to the refugees. On top of that, around 27 members of UNAMIR lost their lives during the mission.
