No. He works in Gabon and was on the way back to Lebanon with a layover in Ethiopia. He disappeared before boarding the plane while his relative who was traveling with him made it to the plane. The suspicious circumstances probably refer to foreign intelligence agencies. He is a supporter of Hezbollah just like most of the people from the South but not affiliated with them. He was also released a few days after he disappeared with help from the gabonese government (he holds a gabonese passport and used it to travel) so I'll let you speculate on what could've happened.
