The combats intensified in the mountain between the Lebanese Forces and the Progressive Socialist Party. Bombs fell in Broumana and close to Moukhtara.

The negotiations that were taking place in Washington, in view of an Israeli troops withdrawal from Lebanon, seemed to have reached some progress.
Back to Lebanon, an attack against an Israeli patrol in Jiyeh provoked the death of three soldiers.

A murderous attack was perpetrated against the United States embassy in Beirut. The Islamic Jihad claimed responsibility for the attack executed using a small truck loaded with explosives driven by a Kamikaze. The embassy’s building was totally devastated, resulting in the death of 61 persons including 17 Americans. Two hours after the attack, President Gemayel arrived at the scene in order to supervise the rescue operations.

While the American Secretary of Sate, George Shultz was undertaking a forcing to reach an agreement between Israel and Lebanon, the mountain went again on fire. The Lebanese Forces and the PSP resumed their combats. The bombardments reached the Kesrouan coastline. They continued in the days to follow causing tens of victims.

The Lebanese-Israeli agreement was signed during two solemn ceremonies taking place simultaneously in Kyriat Shmona and in Khaldeh. The agreement sponsored by the United States was supposed to put an end to the state of war.

The National Salvation Front was born. It was run by Sleiman Frangieh, Rachid Karameh and Walid Joumblatt and was requesting the abrogation of the May 17 Israeli-Lebanese agreement.

The first signs of an imminent Israeli redeployment in the south of the Awali river multiplied. Lebanon urged the United States to intervene in order to delay this initiative.

Taking the Lebanese authorities by surprise, the Israeli Army began its withdrawal from the Chouf and Aley leaving face to face the militia of the PSP and the LF in a merciless battle. The combats raged mainly around Bhamdoun, Souk El Gharb and Kabr Chmoun. A dramatic situation unfolded in the mountain where thousands of people were forced out of their homes. 30 000 people found temporary shelter in Deir El Kamar. The rehousing of the displaced persons caused a complicated problem for the officials.

Two attacks were perpetrated against the general headquarters of the American contingent next to the Beirut International Airport and against a position of the French contingent in Jnah.
The double attack made 241 deaths and 60 injured among the Americans, and 58 deaths and 15 injured among the French. It was a true declaration of war to the political military and even physical presence of the West in Lebanon.
