Israel denied having a hand in the assassination of Hezbollah’s military commander but former intelligence chiefs and political leaders could barely keep the smiles off their faces at the abrupt demise of one of the world’s most wanted terrorists.

Fingers across the Middle East were pointing at Israel after the Damascus bomb attack that killed Imad Mughnieh, described by some Israeli analysts as even more dangerous than Sheikh Hassan Nasrallah, the head of the Shia militant movement.

A statement from the office of Ehud Olmert, the Israeli Prime Minister, denied any knowledge of the attack deep in the heart of the highly policed Syrian capital. “Israel is . . . learning for the first time the details being reported in the media in the past few hours,” it said. “Israel rejects the attempt by terror groups to attribute to it any involvement in this incident.”

Danny Yatom, the former head of Mossad, the Israeli overseas spy network, said: “Mughnieh was one of the most dangerous and cruel terrorists of all time.” Mr Yatom said that there had been “numerous intelligence agencies and countries that have been pursuing him, and the one that was successful in reaching him [had proved itself] to have a high intelligence and operational capability.”

Yoram Schweitzer, an expert on Hezbollah at the Institute for National Security Studies in Tel Aviv, said it was possible that the assassination had been carried out by the Americans, French or even rival Lebanese factions. He said that the United States in particular had been on Mughnieh’s trail for a long time as part of the War on Terror. Mr Yatom said that the attack had dealt a serious blow to Hezbollah, showing that someone had managed to penetrate deep into the ultra-secretive organisation, and added that it would take a long time for it to find an heir.

In Washington a State Department spokesman said: “The world is a better place without this man in it.”

Israeli and American enthusiasm for the killing was matched by outrage from Iran, a key sponsor of Hezbollah, and from the Palestinian militant movement Hamas in Gaza.

Muhammad Ali Hosseini, the Iranian Foreign Ministry spokesman, described Mughniyeh’s brutal life as “a golden page in the history of mankind’s fight against the aggressive and occupying Zionists” and called his death “a clear result and example of organised state terrorism by the Zionist regime.” In Gaza City, Sami Abu Zuhri, a spokeman for Hamas, accused Mossad of carrying out the assassination. He called on the Muslim world to “face up to this Zionist octopus whose crimes are now passing beyond the Palestinian territories”.
