THE southern Lebanese port city of Tyre was completely cut off from the rest of the country by Israeli bombardments today, witnesses and police said to AFP. Israeli jets destroyed a makeshift bridge in Qasimiya, north of Tyre, and the military continued to bombard the road leading out of the city to the south, they said. UN force spokesman Milos Strugar said "the provisional bridge north of Tyre, over the Litani river, and which connects the city to Sidon (further north) has been cut" by the bombing. He said traffic was also blocked from the south by intense shelling on the road leading to the coastal town of Naqura. The makeshift bridge in Qasimiya had been erected after Israeli warplanes destroyed two weeks ago the two bridges in the area which lead to Tyre.
