A stronger version of Resolution 1644 — which accused Syria of deliberately hindering the investigation and increased the scope of the inquiry to include other political killings in Lebanon — was watered down by Algeria , China and Russia . In the preamble of the resolution , the Council reiterated its condemnation of the assassination and other attacks since October 2004 in Lebanon , and stressed that those responsible should be held accountable . It had examined a report of the UNIIIC and commended the commission for working under " difficult circumstances " . All states were required to provide assistance if necessary to the commission . The Lebanese government requested that the investigation be extended , and that an international tribunal be established to try those responsible for the attack . The Council recognised that Syria had made officials available for questioning , but remained concerned at the overall performance of the Syrian authorities to the investigation
