Niger Republic has been thrown into three-day national mourning following the death of former President Mamadou Tandja.
The 82-year-old ex-President died in the capital, Niamey on Tuesday.
His death was announced by the Nigerien government but no cause of death was given.
The former leader had been weakened by illness for several years and had been taken for medical treatment to France, Germany and Morocco.
Tandja was twice elected president of Niger starting 1999 to 2010 before he was overthrown in a coup for attempting to change the constitution to hold onto power.
His ouster paved the way for Issoufou Mahamadou to become president in the 2011 election.
Tandja’s death came just over a month before Niger holds a presidential election.
