On February 27, 1994, at approximately 9:15 a.m., a bomb detonated under the altar of Saydet al-Najat (Our Lady of Deliverance) Church, a Maronite Catholic church in Zouk Mikael, Lebanon, during Sunday Mass while worshippers were receiving communion from Father Antoine Sfeir. More than 200 people were present in the church. The explosion involved C4 explosives and two 81mm mortar rounds; five other explosives were also found in the building. Ten people were killed immediately and 54 were injured; one of the injured later died, bringing the total death toll to 11.
In the aftermath, the Syrian-backed Lebanese government used the bombing as grounds to dissolve the Christian Lebanese Forces (LF) party and arrest its leader, Samir Geagea. On March 19, 1994, LF offices were raided and six people were arrested, including LF secretary general Fouad Malik and members of the LF intelligence apparatus, as well as two members of the Guardians of the Cedars. Around 150 LF members were subsequently detained, and the LF was formally banned on March 23. Geagea himself was arrested on April 21, 1994. The investigation later expanded to include the murder of political rival Dany Chamoun and his family. Geagea and four others were formally indicted for the church bombing on June 13, 1994, and three days later Geagea and twelve others were indicted for the killing of Chamoun, his wife, and two children.
The church bombing trial opened on November 19, 1994. The case relied heavily on a single witness, Girgis Khuri, and was reportedly weakened by the absence of two other LF figures who were in hiding abroad. Commentators described the evidence against Geagea as largely hearsay and circumstantial. The bombing trial was later postponed in disarray after Khuri withdrew his testimony. Separately, on June 24, 1995, Geagea was convicted in the Chamoun murder case and sentenced to death, later commuted to life imprisonment with hard labour; two co-defendants received shorter terms, and ten LF members were sentenced in absentia. Amnesty International condemned that case as seriously flawed, being based entirely on circumstantial evidence. On July 13, 1996, Public Prosecutor Adnan Addoum sought the death penalty for Geagea and several co-defendants in connection with the bombing case, and hard labor for life for others.
Geagea, who maintained his innocence and accused the Syrian-Lebanese security apparatus of orchestrating the bombing as a false flag to justify dissolving the LF, spent 11 years in solitary confinement. Following the 2005 withdrawal of Syrian forces from Lebanon, the case was widely reexamined. On July 18, 2005, the Lebanese Parliament passed an amnesty law that has been characterized as formally exonerating Geagea, with the 1994 trial subsequently described by historians and legal experts as a "show trial" built on manufactured evidence. Geagea was released from solitary confinement on July 26, 2005.
