NATO should be more involved in protecting its members' energy resources, the alliance's top diplomat said Thursday amid concerns that fuel supplies face threats ranging from terrorism to supply cuts by disgruntled exporters.

NATO has a "role to play in this field," Secretary General Jaap de Hoop Scheffer told a gathering of ministers and senior diplomats from almost 50 allied and partner nations.

Some NATO allies want it to consider a military role in protecting pipelines, oil platforms and sea routes bringing oil and gas to Europe and North America. Poland, which is heavily dependent on Russian oil and gas imports, has suggested a pact to support allies whose supplies are
threatened.
