Israel was always supportive of any UN resolution condemning international terrorism, of which it has been a victim. The issue of terror in the sky was also a sore point for Israel ever since an EI-Al airliner was hijacked by the PLO in 1968. The following resolution was unanimously adopted:

The Security Council,

Conscious of the implications of acts of terrorism for international security,

Deeply concerned by all acts of unlawful interference against international civil aviation,

Mindful of the important role of the United Nations in supporting and encouraging efforts by all States and intergovernmental organizations in preventing and eliminating all acts of terrorism, including those involving the use of explosives,

Determined to encourage the promotion of effective measures to prevent acts of terrorism,

Concerned at the ease with which plastic or sheet explosives can be used in acts of terrorism with little risk of detection,

Noting the International Civil Aviation Organization Council resolution of 16 February 1989, in which it urged its member States to expedite current research and development on detection of explosives and on security equipment,

1. Condemns all acts of unlawful interference against the security of civil aviation;

2. Calls upon all States to co-operate in devising and implementing measures to prevent all acts of terrorism, including those involving explosives;

3. Welcomes the work already undertaken by the International Civil Aviation Organization, and by other international organizations, aimed at preventing and eliminating all acts of terrorism, in particular in the field of aviation security;

4. Urges the International Civil Aviation Organization to intensify its work aimed at preventing all acts of terrorism against international civil aviation, and in particular its work on devising an international regime for the marking of plastic or sheet explosives for the purpose of detection;

5. Urges all States, and in particular the producers of plastic or sheet explosives, to intensify research into means of making such explosives more easily detectable, and to co-operate in this endeavour;

6. Calls upon all States to share the results of such research and co-operation with a view to devising, in the International Civil Aviation Organization and other competent international organizations, an international regime for the marking of plastic or sheet explosives for the purpose of detection.
