Beirut, Lebanon - Thousands of people in Beirut are attending the funeral of Lebanon's most eminent Shia cleric, Grand Ayatollah Muhammad Hussein Fadlallah.
A day of national mourning has been declared and a huge crowd has followed the funeral procession in Beirut's southern suburbs.
Tributes have poured in from all over the Arab and Islamic worlds.
The seminaries at Najaf in Iraq, where the ayatollah was born and studied, declared three days of mourning.
The militant Shia movement Hezbollah, with which the ayatollah's name was strongly linked, especially in its early days, has also declared three days of mourning and called for a massive turnout for the funeral.
Regional tributes
The funeral procession is carrying the ayatollah's coffin from his home, through the southern suburbs, to the mosque which he favoured, where he will be laid to rest.
There has been no funeral like it in the southern suburbs, a stronghold for Hezbollah, since that of the former Hezbollah leader Abbas al-Musawi, who was killed by the Israelis in 1992, says the BBC's Jim Muir in Beirut.
Top Iraqi leaders, including Prime Minister Nouri al-Maliki, sent their sympathies and messages of praise.
In the late 1950s, Ayatollah Fadlallah helped found Mr Maliki's Daawa party.
Senior Iranian figures have also sent their condolences, including Ayatollah Ali Khamenei, who said that Ayatollah Fadlallah had always been a patron and supporter of the Islamic resistance in Lebanon - referring to Hezbollah.
The Lebanese government has declared a day of national mourning and flags will be flown at half mast for three days.
Complex figure
Ayatollah Fadlallah, who held the title "sayyed" to indicate claims of direct lineage with the Prophet Mohammed, died at Bahman hospital in Beirut on 4 July after a long illness. He was 74.
He had been a supporter of Iran's Islamic revolution and was customarily described as the spiritual leader of the militant movement Hezbollah when it was formed in 1982 - a claim both he and the group denied.
In later years, his links with Hezbollah became strained as he distanced himself from its ideological links to Iran's Islamic republic, and his views became more moderate.
He was a fierce critic of the United States and Israel, advocating suicide attacks as a means of fighting Israel.
He was branded a terrorist by the US, and named on a 1995 blacklist.
But he had also opposed the call to "jihad," or holy war, by Osama bin Laden and the Afghan Taliban, which he considered to be a sect outside Islam.
Away from politics, the white-bearded Fadlallah was also known for relatively liberal views on women.
He issued a fatwa forbidding female circumcision, and was opposed to the "honour killings" of women by their families.
