ISTANBUL: Hundreds gathered at Istanbul's main court on Friday to support an opposition politician who faces 17 years in prison for a series of tweets criticising the government.

Canan Kaftancioglu, who heads the secular Republican People's Party (CHP)'s Istanbul branch, is accused of "insulting" President Recep Tayyip Erdogan and the Turkish state in tweets posted between 2012 and 2017.

The supporters gathered outside the court chanted "Down with fascism" and held signs reading "We are thirsty for justice".

Kaftancioglu's tweets include an insult directed at Erdogan, and criticism of the death of a 14-year-old boy, who was hit by a tear gas grenade during the mass "Gezi Park" protests of 2013.

She is also accused of "terrorist propaganda" for quoting a member of the outlawed Kurdistan Worker's Party (PKK), which has been fighting a bloody insurgency against the state since 1983.

Her supporters say another tweet, in which she appeared to deny the Armenian genocide, was fake and had been created to smear her.

Kaftancioglu was a key figure in the campaign to elect Ekrem Imamoglu, the new CHP mayor of Istanbul -- whose landslide victory this week marked the first significant defeat for Erdogan since he took power in 2003. —AFP
