A bomb hit a U.N. peacekeeping force patrol on a coastal road in southern Lebanon on Monday, a Lebanese security official said, the second such attack targeting the force in less than a month. The bomb struck the convoy as it was driving through the village of Qassimiyeh near the southern port city of Tyre, the official said, speaking on condition of anonymity because he was not authorized to speak to the media. Lebanon's state-run National News Agency said «a small bomb» exploded near a U.N. peacekeeping force observation post in Qassimiyeh, causing damage but no casualties. It gave no further details.
