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.

In the first attack targeting the U.N. force known as UNIFIL, six peacekeepers belonging to the Spanish contingent were killed June 24 when a bomb struck their armored personnel carrier in southern Lebanon.
