The Lebanese cabinet unanimously agreed during its late Wednesday session to file a complaint with the UN Security Council against Israel for spy rings uncovered in Lebanon, a government source said .
"It was a unanimous vote at the cabinet session. The Lebanese government will send the formal complaint to the UN Security Council this week," the source who requested anonymity told the German Press Agency dpa.
The cabinet decision came shortly after a Lebanese military court on Wednesday sentenced a former school principal to death on charges of spying for Israel in 2008, a judicial source said.
Hasan Ahmed al-Hussein, 58, was found guilty of providing Israel with information about the Lebanese Shiite movement Hezbollah and its leadership, the source said.
Hezbollah fought a 33-day war against Israel in July 2006. Lebanon and Israel technically remain in a state of war.
According to Lebanese law, convicted spies face life in prison with hard labour or the death penalty if found guilty.
Al-Hussein's sentence was the second of its kind in a week. Another Lebanese man had previously been sentenced to death by the military court for spying for Israel's intelligence agency Mossad during the July 2006 war.
Israel has not commented on any of the Lebanese charges.
Since last year, some 70 people have been arrested in Lebanon on charges of spying for Israel.
The 13-member Hezbollah bloc in the Lebanese parliament on Wednesday stressed "the need to uncover and execute individuals charged with collaborating with Israel."
