With Muslims around the world enraged by the carnage in Lebanon, where the death toll has topped 900, the Organisation of the Islamic Conference (OIC) convened an emergency meeting here to map out a unified Islamic response.

Key nations from the 57-nation bloc, including Iran as well as allies of the US "war on terror" such as Turkey and Pakistan, condemned what they called the "relentless Israeli aggression" and called for an immediate truce.

In a joint statement they accused Israel of "blatant and flagrant" human rights violations in carrying out "indiscriminate and massive" air strikes in their three-week-old campaign against the Shia Muslim Hezbollah militia.

"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 unconditional comprehensive ceasefire," they said.

They said Israel should bear "full responsibility for the consequences of its aggression."

The United States has declined to back international calls for a ceasefire and indicated that Israel's ground and air war was justified by the fight against terrorism.

But Malaysian Prime Minister Abdullah Ahwad Badawi, the OIC chairman who called Thursday's meeting, warned that Muslim anger across the world was deepening over the bloodshed in Lebanon.

"Muslims are angry even in moderate Muslim countries," Abdullah told a press conference after a day of talks that led to the group's statement.

"We fear that a new wave of angry people may join the ranks of terrorism and take their own actions," he said.

Ekmeleddin Ihsanoglu, the OIC's Turkish secretary general, earlier told delegates that the "Islamic Ummah (community) is outraged."

"They are perplexed in the face of gross double standards applied by the international community," Ihsanoglu said.

"Anger is spreading all over the Muslim world. I am afraid that the anger of the Muslim masses is being transformed into permanent hatred against the aggressors and their explicit and implicit protectors."

One of the key Islamic leaders at the one-day meeting, Iranian President Mahmoud Ahmadinejad, reportedly said behind closed doors that wiping out Israel would solve the current crisis.
