Protestes march past a billboard depicting slain Gen. Wissam al-Hassan with Arabic that reads, &quot;the martyr of commitment to state and law,&quot; in Martyrs&#x27; Square during a protest against the killing of the country&#x27;s intelligence chief, al-Hassan and at least seven others in Beirut, Lebanon, Saturday, Oct. 20, 2012. The government declared a national day of mourning for the victims on Saturday, but protesters took to the streets, burning tires and setting up roadblocks around the country in a sign of the boiling anger over the massive bomb that Lebanon&#x27;s prime minister linked to the civil war in neighboring Syria.
