The U.N.-backed Lebanon Tribunal on Friday sentenced a Hezbollah member convicted of conspiring to kill former Lebanese Prime Minister Rafik al-Hariri in a 2005 bombing to five terms of life imprisonment.

Salim Jamil Ayyash was found guilty in August of homicide and committing a terrorist act over the deaths of Hariri and 21 others. His trial was conducted in absentia and Ayyash remains at large.

The five life terms are to be served concurrently.
