the Blue Line as confirmed by UNIFIL. One Israeli was killed by Lebanese army fire and three Lebanese died when the Israel Defense Forces (IDF) responded. Lebanese Information Minister Tarek Mitri stated despite the fact that Lebanon accepted earlier the Blue line "The area where the tree was to be cut yesterday […] is south of the Blue Line but is Lebanese territory." UNIFIL determined that the Israeli troops were on Israeli territory. 2011 Israel–Lebanon border clash On 1 August 2011, UNIFIL confirmed a border incident in which no one was hurt.
