BEIRUT, Jan. 24 (Xinhua) -- An Israeli tank on Tuesday crossed the "technical fence" along the border with Lebanon, prompting high alertness from the Lebanese army, the National News Agency reported.
This is the fourth similar incident on the Lebanon-Israel border within a week, the report said, adding that the Israeli tank did not violate the Blue Line, which is a demarcation line between Lebanon and Israel as well as Lebanon and the Golan Heights published by the United Nations in 2000.
Israel built the "technical fence" with electrified wires along the 49-mile (79-km) border with Lebanon in 2001, about 50 meters south of the Blue Line.
Also on Tuesday, a team from the United Nations Interim Force in Lebanon (UNIFIL) used a helicopter to conduct an inspection tour of the Blue Line after UNIFIL spokesperson Andrea Tenenti warned last week against the escalation of tensions along the border.
The Israel-Lebanon border has been relatively calm since Israel fought a war with Lebanon's Hezbollah forces in 2006.
