Israeli jets and artillery bombarded southern Lebanese border areas today, witnesses and the Israeli military said.
Witnesses said areas near Rmeish, Aita, Yaroun and Ghajar, towns along different parts of the Lebanese border with Israel, were hit. The Israeli army said it fired at Hizbollah positions in southern Lebanon.
Earlier, Israeli aircraft fired missiles two Palestinian militant bases in Lebanon, witnesses and a security source said, hours after rockets fired into northern Israel wounded an Israeli soldier.
The source said at least eight Israeli missiles were fired in two sorties against one military base run by the Syrian-backed Popular Front for the Liberation of Palestinian-General Command (PFLP-GC) near the town of Luci in the eastern Bekaa Valley.
It was not immediately clear if there were any casualties, but witnesses saw ambulances rushing to the area.
An Israeli army spokesman had no immediate comment. Security sources said later that Israeli jets had fired missiles at a second Palestinian militant base in Lebanon.
Witnesses saw smoke rising from the Naameh base just outside Beirut, run by the same group
The exchange came two days after a senior Islamic Jihad official and his brother were killed in a car bombing in southern Lebanon that the Palestinian group blamed on Israel.
Lebanon's Hizbollah guerrilla group, which controls the Lebanese side of the border, had also blamed Israel for the assassination and Islamic Jihad officials had sworn revenge.
