Timeline: Lebanon Since 2005 Agence France-Presse BEIRUT - Lebanon, whose capital Beirut was rocked on Tuesday by huge explosions that killed dozens, is mired in its worst economic crisis in decades andunprecedented social unrest. A timeline since 2005: Assassination of Rafik Hariri A massive suicide bomb tears through former prime minister Rafic Hariri's armored convoy on the Beirut seafront on Feb. 14, 2005, killing him and 21 other people. Opposition leaders blame Syria, but Damascus denies any role. Lebanon's powerful Shiite movement Hezbollah is also heavily suspected. Amid a groundswell of protests, Syrian troops quit Lebanon on April 26 after a 29-year deployment which had peaked at 40,000 troops. A U.N. tribunal trying the four suspects accused of the assassination is set to deliver its verdict this coming Friday. Hezbollah chief Hassan Nasrallah has refused to hand over the defendants. .
