Christophe

Christophe Gleizes, who is 36, was sentenced on Sunday, after being found guilty of holding exchanges with a proponent of self-determination for Algeria's Kabyle minority.

"The imprisonment of a journalist for carrying out his profession is a red line that must never be crossed. Christophe Gleizes must be given back his freedom, his family and his writing," journalists' representatives from around 40 different French media said in a statement.

"Nothing can justify the ordeal that Christophe is going through now," his family said.

"The last vestiges of working-class politics were imperiously wiped out," wrote Christophe Jaffrelot and Pratinav Anil in their book on the period they call "India's first dictatorship".

Christophe Hodder, a UN climate security and environmental adviser, warns that the unchecked construction boom could lead to long-term environmental consequences.
