Speaking in Malaysia, the secretary general of the 57-nation Organization of the Islamic Conference (OIC),Ekmeleddin Ihsanoglu, said "many" countries said they were prepared to send troops for an enlarged UN Interim Force in Lebanon (UNIFIL) but declined to give details.
Malaysia is hosting nearly 20 Muslim nations at special crisis talks to demand an end to Israel's military offensives in Lebanon and Gaza.
The head of the OIC also said the Islamic world was "outraged" over international "double standards" towards the Israeli offensive in Lebanon and warned that another failed peace initiative would only fuel more violence and terror and threaten global peace and stability.
Later, in a draft statement seen by AFP, the Muslim nations demanded an immediate Middle East ceasefire backed by the UN Security Council.
"We demand that the UN Security Council fulfil its responsibility for the maintenance of international peace and security without any further delay by deciding on and enforcing an immediate and comprehensive ceasefire," it said.
The emergency meeting of OIC nations was to issue a final statement later on Thursday.
Meanwhile, in a video statement to the conference, Lebanese Prime Minister Fuad Siniora said Lebanon's death toll in more than three weeks of Israel-Hezbollah fighting had reached more than 900, with 3,000 injured.
'Israel near goal'
Prime Minister Ehud Olmert has said in a newspaper interview published today that Israel was "very close" to its goal in Lebanon and the United Nations would likely vote on a truce next week.
Mr Olmert told Italy's Corriere della Sera newspaper that US Secretary of State Condoleezza Rice did not expect a truce to end fighting in Lebanon in the next few days.
"It's more likely that there will be a vote in the United Nations next week," he was quoted as saying. "The process is long. From our standpoint, we will cooperate with any reasonable proposal."
Mr Olmert reiterated that Israel will keep fighting Hezbollah guerrillas until a strong international force is deployed in south Lebanon.
Air raids
The Israeli air raids in Lebanon were in areas near Lweizeh, Jbaa, Sarba and Ein Bousuar, more than 20 km from the northernmost tip of Israel.
On the ground, fierce battles raged between Hezbollah guerrillas and Israeli soldiers in towns along the Israel-Lebanon border.
Israel pressed into Lebanon with a force 8,000 strong.
In addition, at least four loud explosions echoed across Beirut this morning as Israeli jets struck a Hezbollah-dominated southern suburb for the first time in days.
Jets also hit a bridge in the northern region of Akkar.
Lebanese security officials said an Israeli missile slammed into a house in the Lebanese border village of Taibeh early today, killing a family of three.
The village was also the scene of fierce clashes between Hezbollah guerrillas and Israeli ground troops today.
Seven civilians were killed in an intense Israeli bombardment of the Tyre region in south Lebanon from the air, sea and ground, police said.
An 80-year-old couple died when their house in Tair Harfa collapsed after being hit and five people were crushed to death under the rubble of a three storey house in the village of Yarun, police said.
Lebanese police said that from 6pm (local time), the Israeli air force carried out 27 raids on villages south and east of Tyre, while more than 150 mortars pounded the area.
"The Tyre region is on fire," said a police officer.
Hezbollah television reported "fierce battles with an enemy unit on the eastern entrance of the village of Aita al-Shaab, trying to infiltrate the area".
It said the guerrillas destroyed an Israeli tank in the area, and were preventing Israeli troops from retrieving the tank and some wounded soldiers.
UN meeting delayed again
Israel’s airstrikes resumed as the United Nations called off a meeting on an international force for Lebanon.
A UN spokesman said the meeting has been postponed until the political elements of a ceasefire accord are agreed.
France had declared it would boycott the meeting, calling the event "premature".
It wants the UN Security Council to have the political framework in place before an international force is sent.
But there has been progress on the text of a Security Council resolution to end the violence.
The British ambassador to the UN said France, Britain, China, Russia and the United States were close to agreement on a peace plan.
He believes the entire Security Council can start talking about the resolution by tomorrow.
The United States, France and Britain are hoping for a UN Security Council resolution within a week.
The text is expected to call for a truce and more UN peacekeepers in Lebanon until an international force can be formed.
Diplomats say the US and France are rapidly working out their differences on an initial resolution that would also call for the creation of a buffer zone and the disarming of Hezbollah guerrillas.
But France has made it clear it will not join an international force without a truce and an agreement in principle on the political framework of a long-term peace deal by Israel, Hezbollah and the Beirut government.
Once fighting has ended negotiations would begin at the UN on a second resolution setting out a permanent ceasefire that all combatants could accept.
