Siniora also said in a video statement to a meeting of the Organization of the Islamic Conference (OIC) that about 3,000 people had been wounded.

A third of the casualties were children under 12, said Siniora, adding that 1 million people, or a quarter of Lebanon's population, had been displaced in the violence.

The Lebanese prime minister also said that the continuous Israeli massive offensive had done heavy damages to Lebanon's infrastructure and battered the country's economy.

Lebanese Minister of Public Health Mohammed Jawad Khalife said earlier that about 750 Lebanese had been killed including a number of people still buried in the rubble.

Fifty-six Israelis have also been killed in the conflict which erupted on July 12 following the capture of two Israeli soldiers by Hezbollah guerillas.

Siniora made the statements as the OIC started a special session over the Lebanon crisis in Malaysia.

Member states of the world largest Muslim body demanded an immediate ceasefire in Lebanon and a UN stabilization force.
