A Lebanese journalist and three Lebanese soldiers were killed on Tuesday when Lebanese and Israeli troops exchange fires in the border region, unnamed security sources told Xinhua.
A senior Israeli officer was also killed in the deadliest clashes since the 2006 war between Lebanon's shiite Hezbollah group and Israel, according to sources from both sides.
The clashes erupted in the southern village of Edaysaeh after Israeli soldiers entered Lebanese territories to uproot a tree, security sources said.
General Said Eid, Lebanon's higher defense council chief, said that Lebanon is ready to confront "Israeli aggression by all available means."
Eid added Lebanon planned to file a complaint over the incident to the UN Security Council.
The UN Interim Forces in Lebanon visited the scene of the clashes and urged both sides to stop the violence.
