UNITED NATIONS (AP) – The United States, France and Britain circulated a draft resolution Tuesday threatening sanctions against Syria if it doesn”t cooperate with a U.N. investigation into the assassination of Lebanon”s former prime minister.

The draft resolution orders Syria to detain officials or individuals considered possible suspects in the Feb. 14 assassination of Rafik Hariri &#34and make them fully and unconditionally available&#34 to the U.N. investigating commission.

It states that Syria must allow the commission to interview Syrians that it considers relevant to the inquiry &#34outside Syria and/or outside the presence of any other Syrian official if the commission so requests.&#34

If Syria does not fully cooperate with the investigation, the draft says the council intends to consider &#34further measures,&#34 including sanctions, &#34to ensure compliance by Syria.&#34

The draft resolution also calls for anyone designated by the commission as suspected of involvement in Hariri”s assassination to be subject to a travel ban and to have their assets frozen.

The proposed resolution would be under Chapter VII of the U.N. Charter which is militarily enforceable.

The United States and France circulated the resolution hours after the chief U.N. investigator, Detlev Mehlis, briefed the council on his report which implicated top Syrian and Lebanese security officials in the car bomb that killed Hariri and 20 other people.

Mehlis has said repeatedly that Syria had not fully cooperated and continuing the probe would be near impossible if Damascus didn”t change course. He took that message directly to the council in his briefing, urging Syria to help &#34fill in the gaps&#34 about who orchestrated the bombing, both by cooperating with a probe and studying the crime itself.

The draft resolution declares that &#34it is unacceptable that anyone should escape accountability for an act of terrorism because of his own obstruction of the investigation or failure to cooperate in good faith.&#34

It would endorse the Mehlis commission”s conclusion &#34based on Syria”s suspected involvement in this terrorist act and lack of adequate cooperation to the inquiry to date, that it is incumbent upon the Syrian authorities to clarify a considerable part of the questions which remain unresolved.&#34

Under the draft”s provisions, Syria would also be required to renounce terrorism and &#34commit itself definitively to cease all support for all forms of terrorist action and all assistance to terrorist groups and to demonstrate this undertaking through concrete actions.&#34

U.S. Ambassador John Bolton said the Security Council would hold a meeting on Monday at ministerial level to consider the resolution. U.N. diplomats said they expect the ministers to adopt the resolution, which would give added weight to the measure and increase pressure on Syria.
