The carnage began immediately. It was to continue without interruption till Saturday noon. Night brought no respite; the Lebanses Forces liaison officer asked for illumination and the Israelis duly obliged with flares, first from mortars and then from planes.
From there, small units of Lebanese Forces militiamen, roughly 150 men each, were sent into Sabra and Shatila, which the Israeli army kept illuminated through the night with flares.
and while Israeli troops fired a stream of flares over the Palestinian refugee camps in the Sabra and Shatila districts of West Beirut, the Israeli's Christian Lebanese allies carried out a massacre of innocents there which was to shock the whole world.

From July 1981 to June 1982, under cover of the ceasefire, the PLO pursued its acts of terror against Israel, resulting in 26 deaths and 264 injured.
The most immediate problem was the PLO's military infrastructure, which posed a standing threat to the security of northern Israeli settlements.

Indeed, subsequent Israeli propaganda notwithstanding, the border between July 1981 and June 1982 enjoyed a state of calm unprecedented since 1968.
