Israeli helicopter gunships rocketed the Lebanese shop of a boat dealer suspected of links with Palestine Liberation Organization guerrillas. Five people were wounded and the store in Sidon was demolished, police said. The shop owner, Mahmoud Hijazi, is suspected of renting motorboats to PLO members, police said. Hijazi's boats, anchored off the beach, were not hit in the raid. Meanwhile, Israeli-backed south Lebanese militia members killed three guerrillas who apparently landed in a boat on the Mediterranean coast just north of Israel, the army command said.
