Samir Geagea and president Amine Gemayel decided not to accept the agreement, with Geagea's LF faction attacking Hobeika's LF Loyalists' positions in east Beirut on 8 January 1986, being backed by the Lebanese Army's 9th Brigade. On 13 January, in a bid to greatly extend Hobeika's own power, his faction stepped up the conflict by assaulting the positions held by the Kataeb Party militia loyal to Amine Gemayel. The Kataeb party leader, Amine Gemayel, was at the time serving as president of Lebanon.
