Parliament used the truce to amend Article 73 of the constitution so that Frangieh's successor could be elected early: on 9 April according to Hanf, 10 April according to Yara El Khoury. The truce had coincided with the arrival on 31 March of the US envoy Dean Brown.

Historians date the battle of Zahleh from this day, when Lebanese Forces fighters beat off a Syrian attack on the town and a siege of some 90 days began. Ménargues says Syrian heavy guns killed 50 and wounded over 200 that day in Zahleh and the Christian zone north of Beirut.

According to Picard, Hamid Frangieh negotiated Lebanon's financial agreements with France, which she places in 1943 rather than 1948.

The meetings produced no agreement (Hanf).

Under the 5 April accord, reached by Amal, the PLO and the pro-Syrian Palestinian National Salvation Front with the Syrian general Ghazi Kanaan present, the blockade was to be lifted, the wounded taken out and the PLO was to leave three villages near Sidon. Food and medicine then reached Chatila and Bourj al-Barajneh, the first since March. Picard dates the end of the siege to an Amal-Palestinian agreement of 11 September 1987; Hanf has Amal lifting the blockade only on 18 January 1988.

Hanf: when Damascus protested, Paris called envoy Deniau's description of Syria as the aggressor in Lebanon his 'private opinion'.
