TYRE, Lebanon (AP) — More than 4,200 people have been displaced from villages in south Lebanon by clashes on the border with Israel, and local officials said Friday that they are ill-prepared for the much larger exodus that would ensue if the limited conflict escalates to an all-out war.

Some 1,500 of the displaced are staying in three schools in the coastal city of Tyre, about 20 kilometers (12 miles) north of the border.
