On October 7, 2004 the UN Secretary General Kofi Annan reported to the Security Council regarding the lack of compliance with Resolution 1559. Mr. Annan concluded his report by saying: "It is time, 14 years after the end of hostilities and four years after the Israeli withdrawal from Lebanon, for all parties concerned to set aside the remaining vestiges of the past. The withdrawal of foreign forces and the disbandment and disarmament of militias would, with finality, end that sad chapter of Lebanese history."
The January 20, 2005 UN Secretary-General's report on Lebanon stated that "The continually asserted position of the Government of Lebanon that the Blue Line is not valid in the Shab'a farms area is not compatible with Security Council resolutions. The Council has recognized the Blue Line as valid for purposes of confirming Israel▓s withdrawal pursuant to resolution 425 (1978). The UN Security Council has repeatedly requested that all parties respect the Blue Line in its entirety."[5]
On January 28, 2005 UN Security Council Resolution 1583 called upon the Government of Lebanon to fully extend and exercise its sole and effective authority throughout the south, including through the deployment of sufficient numbers of Lebanese armed and security forces, to ensure a calm environment throughout the area, including along the Blue Line, and to exert control over the use of force on its territory and from it.
Syria made few moves to comply with the resolution until the assassination of Rafik Hariri, the former Prime Minister of Lebanon, on February 14, 2005. International pressure to withdraw intensified and public perception in Lebanon turned strongly against Syria, evidenced by mass demonstrations that were labeled the Cedar Revolution. President Bashar al-Assad of Syria announced on March 5, 2005 that he planned to "bring his forces home." The withdrawal, involving about 14,000 troops, took about seven weeks to complete.
On April 26, 2005, after 29 years of military action in Lebanon, the last Syrian troops left Lebanon. Syrian military and intelligence facilities, after the destruction of sensitive documents or the transportation of logistical material, were turned over to Lebanese counterparts. This action left the Lebanese government as the main violator of the resolution due to its refusal to dismantle the pro-Syrian Palestinian and Hezbollah militias.
On December 27, 2005 Katyusha rockets fired from Hezbollah territory smashed into houses in the Israeli city of Kiryat Shmona wounding three people [5]. UN Secretary General Kofi Annan called on the Lebanese government "to extend its control over all its territory, to exert its monopoly on the use of force, and to put an end to all such attacks" [6].
On January 23, 2006 the UN Security Council called on the Government of Lebanon to make more progress in controlling its territory and disbanding militias, while also calling on Syria to cooperate with those efforts. In a statement read out by its January President, Augustine Mahiga of Tanzania, the Council also called on Syria to take measures to stop movements of arms and personnel into Lebanon.[7]
