There has been an incident on the Lebanese border, in which Lebanese Army troops fired on Israeli soldiers who were cutting trees near the border fence. The soldiers were on the Lebanese side of the fence, but on the Israeli side of the border.
More precisely, the Lebanese targeted the Israeli commanders who were supervising the operation, and at least one, Lt. Col. Dov Harari, was killed. Another officer, Capt. Ezra Lakia, was critically wounded.
This is the worst such incident since 2006.
Here is a link to an Israeli blog where news is being presented live as events unfold.
Update [0930 PDT]: The IDF says it was Hizballah fighters in LAF (Lebanese Army) uniforms “some LAF units are strongly influenced by Hizballah”.
They are calling it an ‘ambush’. It looks like cold-blooded murder to me.
