Israel may face reprisal attacks after Hezbollah claimed an Israeli helicopter strike killed six of their fighters, including the son of the group's late military leader.
The strike, which is claimed to have killed Jihad Moughniyah, occurred in the province of Quneitra, near the Israeli-occupied Golan Heights, Lebanese sources said.
Moughniyah's father, Hezbollah leader Imad Moughniyah, was on the United States' most wanted list for attacks on Israeli and Western targets before being killed by a bomb in Damascus in 2008.
The convoy attack came days after Hezbollah leader Sayyed Hassan claimed frequent Israeli strikes in Syria were a major aggression and said Syria and its allies had the right to respond.
Hezbollah has been fighting alongside President Bashar al-Assad's forces in Syria's four-year war.
