In May 2008, after the government decided to disband Hezbollah's communications network (a decision it later rescinded), violent clashes broke out briefly between government allies and opposition forces, before control of the city was handed over to the Lebanese Army. After this a national dialogue conference was held in Doha at the invitation of the Prince of Qatar. The conference agreed to appoint a new president of Lebanon and to establish a new national government involving all the political adversaries. As a result of the Doha Agreement, the opposition's barricades were dismantled and so were the opposition's protest camps in Martyrs' Square. On 19 October 2012, a car bomb killed eight people in the Beirut's neighbourhood of Achrafiyeh, including Brigadier General Wissam al-Hassan, chief of the Intelligence Bureau of the Internal Security Forces. In addition, 78 others were wounded in the bombing. It was the largest attack in the capital since 2008. On 27 December 2013, a car bomb exploded in the Central District killing at least five people, including the former Lebanese ambassador to the U.S. Mohamad Chatah, and wounding 71 others.
