The Council recalled various General Assembly and other resolutions, condemning all incidents of hostage-taking and abductions and calling for the immediate safe release of hostages wherever they are. It also called on States to use their political influence, in accordance with the United Nations Charter, to secure the safe release of hostages and abducted persons.
