Speaking at the IDF induction center on Sunday, Liberman said Israel has no reason to interfere in the Syrian conflict, but will operate to stop the transfer of advanced weapons to Hezbollah, largely financed by Iran. He was killed on a Hezbollah base near Damascus airport last May, and the militia said he died in the shelling by a Sunni rebel group.
Prime Minister Benjamin Netanyahu told reporters on Tuesday that Israel was not told by Russian Federation to put a halt to missions inside Syrian territory.
Eisenkot said Israel "believes that he was killed by his own officers".
A still image taken from a video uploaded on social media on March 20, 2017, shows fighters, said to be members of Ahrar Al Sham group, holding up their weapons and cheering, said to be in Damascus, Syria.
Earlier this month, the pan-Arab news network al-Arabiya said its investigation into Badreddine's death had concluded that the commander was killed on the orders of Hezbollah leader Hassan Nasrallah.
Israeli intelligence believes Badreddine had been feuding with Iranian military commanders in Syria over the heavy losses his group had suffered on the battlefield.
Mustafa Badreddine was killed in an explosion in the Syrian capital in May 2016.
The Israeli military said Tuesday that his death, blamed on Israel, was in fact an inside assassination.
The same day, Russia's Foreign Ministry summoned the Israeli ambassador to Moscow, Gary Koren, to demand explanations for the airstrikes Israel conducted near the Syrian city of Palmyra on Friday morning.
Israeli Prime Minister Benjamin Netanyahu and Russian President Vladimir Putin have held a series of talks on avoiding accidental clashes, and a "hotline" has been set up between the two countries.
Israeli Defense Minister Avigdor Lieberman threatened to destroy Syria's air defense systems if Israeli jets were again targeted by regime forces. Despite strong geopolitical differences in Syria between the two countries, Israel and Russian Federation have established a working mechanism between their militaries to prevent any possible clashes or incidents.
