Lebanese prominent Shiite Cleric Sayyed Mohammad Hussein Fadlallah on Sunday died of internal bleeding that he suffered a few days ago, at the age of 75.

Medical sources confirmed that Fadlallah died of internal bleeding at Beirut's Bahman Hospital in Beirut's Shiite-inhabited southern suburb of Dahiya.

He has been hospitalized several times in the past few months. On Friday, he was admitted to intensive care as his health deteriorated.

Fadlallah, from a Lebanese family, was born in Najaf of Iraq and studied Islamic science in Najaf before moving to Lebanon in 1952.

In the following years, he gave lectures, wrote dozens of books, founded several Islamic religious schools and established the Mabarrat Association.

Through that association he established a public library, a women's cultural center and a medical clinic.

He supported the ideals of Iran's Islamic Revolution and advocated the corresponding Islamic movement in Lebanon.

Fadlallah was the target of several assassination attempts, including the allegedly CIA-sponsored and Saudi-funded Beirut car bombing that killed 80 people on March 8, 1985.

He was also known as the spiritual leader of Hezbollah, the Lebanese Shiite armed group.
