FACTBOX-Key facts on Jean-Pierre Bemba

(Reuters) - Heavy gun and mortar fire shook Congo's capital Kinshasa on Friday in a second day of bloodshed between government troops and forces of former rebel leader Jean-Pierre Bemba, who lost last year's presidential election.

Here are some key facts on Jean-Pierre Bemba:

* EARLY LIFE:

-- Bemba was born in late 1962 with a silver spoon in his mouth. His father Saolona's SCIBE Zaire conglomerate was Congo's biggest company with more than 10,000 employees in the days of dictator Mobutu Sese Seko, and the family comes from Mobutu's home province of Equateur.

-- He was sent to boarding school in Brussels at the age of six and, after getting an MBA, returned to Kinshasa to set up his own air cargo and cellphone companies, soon becoming a millionaire in his own right.

* OPPOSITION:

-- In 1997, when Mobutu was overthrown, Bemba went into exile. During Congo's 1998-2003 war Bemba headed the Ugandan-backed Congolese Liberation Movement (MLC) and, with Ugandan army backing, seized vast swathes of eastern Congo, financing much of his war through sales of diamonds.

* SHORT-LIVED PEACE:

-- His was the first rebel group to sign peace deals with Joseph Kabila. The MLC became a political party and in 2003 Bemba was sworn in as vice-president.
