With the bodies of its fighters still strewn on the battlefield, Hezbollah must bury its dead and provide succour to its supporters who bore the brunt of Israel’s offensive, as the first steps on a long and costly road to recovery, four senior officials said.

Hezbollah believes the number of its fighters killed during 14 months of hostilities could reach several thousand, with the vast majority killed since Israel went on the offensive in September, three sources familiar with its operations say, citing previously unreported internal estimates.

One source said the Iran-backed group may have lost up to 4,000 people – well over 10 times the number killed in its month-long 2006 war with Israel. So far, Lebanese authorities have said some 3,800 people were killed in the current hostilities, without distinguishing fighters from civilians.

Hezbollah emerges shaken from top to bottom, its leadership still reeling from the killing of its former leader Sayyed Hassan Nasrallah and its supporters made homeless en masse by the carpet bombing of Beirut’s southern suburbs and the destruction of entire villages in the south.

With a ceasefire taking hold on Wednesday, Hezbollah’s agenda includes working to re-establish its organisational structure fully, probing security breaches that helped Israel land so many painful blows, and a full review of the last year including its mistakes in underestimating Israel’s technological capabilities, three other sources familiar with the group’s thinking said.

For this story Reuters spoke to a dozen people who together provided details of some of the challenges facing Hezbollah as it seeks to pick itself up after the war. Most asked not to be named to speak about sensitive matters.

Hassan Fadallah, a senior Hezbollah politician, told Reuters the priority will be “the people.”

Israel’s campaign has focused largely on Hezbollah’s Shi’ite Muslim heartlands, where its supporters were badly hit. They include people still nursing casualties from Israel’s attack on its mobile communications devices in September.

The Israeli offensive displaced more than 1 million people, the bulk of them from areas where Hezbollah has sway.

A senior Lebanese official familiar with Hezbollah thinking said the group’s focus would be squarely on securing their return and rebuilding their homes: “Hezbollah is like a wounded man. Does a wounded man get up and fight? A wounded man needs to tend to his wounds.”

The official expected Hezbollah to carry out a wide-ranging policy review after the war, dealing with all major issues: Israel, its weapons, and the internal politics of Lebanon, where its weapons have long been a point of conflict.

Iran, which established Hezbollah in 1982, has promised to help with reconstruction. The costs are immense: The World Bank estimates $2.8 billion in damage to housing alone in Lebanon, with 99,000 homes partially or fully destroyed.

The senior Lebanese official said Tehran has a variety of ways to get funds to Hezbollah, without giving details.

Parliament Speaker Nabih Berri, a close Hezbollah ally, is urging wealthy Lebanese Shi’ites in the diaspora to send funds to help the displaced, two Lebanese officials said.
