NABATIYEH, Lebanon (AP) _ Israeli aircraft rocketed bases of the Shiite Moslem guerrilla group Hezbollah in southeastern Lebanon this morning. There were no immediate reports of casualties.

Reporters in Nabatiyeh said at least two hraft with anti-aircraft guns. No hits were observed.

An Israeli army communique said Hezbollah targets were struck in Mazraat Ayn Busiwar, 14 miles north of the Israeli border. ''All targets were hit and our planes returned safely to base,'' the communique said.

It did say what type aircraft were involved in the raid and did not mention casualties or damage.

A police spokesman in Lebanon said Hezbollah fighters would not allow police into the area and that it was not known if anyone was killed or injured.

''We'll only know if they evacuate any wounded to hospitals in Sidon,'' he said, speaking on condition of anonymity.

An Israeli army spokesman, who spoke on condition of anonymity, said several targets were struck. He refused to elaborate.

No reason for the raid was given, but military officials have several times accused guerrillas of Hezbollah of taking part in attacks in the security zone or of attempting to infiltrate Israel through the border strip.

Israel established the 6- to 10-mile-wide zone after pulling the bulk of its troops out of Lebanon in 1985, following a three-year occupation of the south. The area is intended to prevent cross-border raids on Israel.

It was Israel's 13th bombing raid in Lebanon this year and the first since September 20 when planes struck a Palestinian base at Naameh, just south of the Lebanese capital of Beirut.

By police count, 17 people have been killed and 103 wounded in the previous strikes.
