The Special Tribunal for Lebanon announced Friday that it cannot provide any comment on Mustafa Badreddine's death before the issuance of a judicial ruling.
Top Hezbollah commander Mustafa Badreddine has been killed, the Shiite party said on Friday, the biggest blow since its military chief was killed in 2008.
Badreddine, 55, was one of the highest ranking officials in the group, and assessed by the US government to be responsible for Hezbollah's military operations in Syria, where it is fighting alongside the Syrian President Bashar al-Assad.
Badreddine was also charged with leading the assassination of former Lebanese Prime Minister Rafik Hariri in the Lebanese capital, Beirut, in 2005.
Badreddine was tried in absentia by the ongoing STL, in The Hague, over the killing of Hariri.
He was indicted on four charges and was said by the tribunal to be "the overall controller of the operation" to kill Hariri.
Three other Hezbollah members also stand accused of their role in the assassination.
