Israel renewed its bombardment against southern Lebanon Wednesday night, the pan-Arab al-Jazeera satellite channel reported.

Explosions were heard in southern Lebanon in the footage of al-Jazeera.

Meanwhile, Israel's newspaper Ha'aretz reported that Israel Defense Forces (IDF) began operation against eastern section of Lebanon security zone.

The fresh raid came about two hours after Lebanon's Hezbollah leader Hassan Nasrallah said in a televised speech that its group's ability to fire rockets against Israeli cities was not harmed by an over-four-week-long Israeli offensive.

Earlier on Wednesday, the Israeli security cabinet approved expanding the army's ground operations in south Lebanon, under which Israeli troops are to push to the Litani River, about 20 km from the Israel-Lebanon border, local media reported.

Over 100 Israelis and about 1,000 Lebanese have been killed in the 29 days of violence so far since Israel-Hezbollah violence was erupted on July 12 when the Shiite group kidnapped two Israeli soldiers and killed eight others.
