Israeli and Lebanese armed forces faced off along Israel's northern border near the disputed Har Dov region on Tuesday, according to Lebanese media. The Lebanese army rushed troops to the area after four Israeli tanks reportedly entered a section of Har Dov that was supposed to remain demilitarized. The Lebanese also claimed that Israeli aircraft entered Lebanese airspace in the vicinity numerous times throughout the day. Israeli military officials said they were monitoring the situation, but denied that there was any increase in tension along the border. The incident comes just a week after Israeli officials complained to the UN that its peacekeepers in southern Lebanon were doing little or nothing to prevent Hizballah from reestablishing its power base there.
