Although Syria was widely blamed for Mr. Hariri’s death, there is increasing speculation that the Netherlands-based Special Tribunal for Lebanon, which is handling the investigation and any subsequent legal proceedings, has uncovered evidence implicating Hezbollah in the assassination.
Hezbollah has denied any involvement, insisting that Israel killed Hariri. The tribunal is thought to be preparing to issue its first indictments against individual members of Hezbollah before the end of the year.
With the spotlight on Hezbollah, Syria has been given some breathing space, allowing it to patch up relations with Arab states like Saudi Arabia and regain some of the influence in Lebanon it lost in the wake of Hariri’s death. The United States also has stepped up its diplomatic engagement with Syria, hoping to revive peace talks with Israel and to gradually wean Damascus from Tehran’s tight embrace.
