The Doha Agreement

The Doha Agreement was an agreement reached by rival Lebanese factions on 21 May 2008 in Doha, Qatar. This agreement marked the end of an 18-month-long political crisis in Lebanon.

After battles broke out in Lebanon because of the ongoing political crisis, Qatar's Emir Sheikh Hamad bin Khalifa Al Thani (ruling Emir of Qatar from 1995 to 2013) invited all Lebanese political parties to its capital Doha to seek an agreement, in order to end the ongoing political crisis and avoid an eventual civil war.

Lebanon's ongoing political crisis suddenly exploded when the government issued two decisions to remove Hezbollah's telecommunications network and resign the Rafik Hariri International Airport's head of security after finding out about a Hezbollah surveillance camera monitoring the western runway number 17, which is used primarily for executive jets. In response to these decisions, mushrooming riots swept across Beirut resulting in heavy clashes between Hezbollah and the majority, afterwards Hezbollah militants invaded and took control of western Beirut. This was the first time after the Lebanese Civil War (1975-1990) weapons were used by Hezbollah on the internal front. Battles moved to several areas in the country including Mount Lebanon and the North, and 300 people are estimated to have died in the operation.The Arab council quickly acted to stop the violence. Based on the Arab initiative regarding containment of the Lebanese crisis, and in pursuance of the agreement concluded among the Lebanese parties in Beirut on 15 May 2008, under the aegis of the Arab Ministerial Committee an agreement was reached.

The Lebanese National Dialogue Conference was held in Doha between 16 May and 21 May 2008, with the participation of the Lebanese political leaders who are members of the National Dialogue Conference and who have asserted their commitment to saving Lebanon and ending the current political crisis and its dangerous consequences for the coexistence formula and civil peace among the Lebanese, as well as their commitment to the principles enshrined by the Lebanese constitution and the Taif Agreement; and as a result of this Conference, as well as of the bilateral and collective meetings and consultations between the president and members of the Arab Ministerial Committee and all parties that took part in this Conference the parties were able to reach an agreement.
