KIEV: Thousands of people rallied on Sunday (Dec 10) in central Kiev to demand the release of detained former Georgian leader Mikheil Saakashvili and the impeachment of his rival, Ukrainian President Petro Poroshenko.
Saakashvili, 49, who entered Ukrainian politics after serving as president of Georgia, was arrested last week in Kiev, accused of trying to stage a coup sponsored by Russia.
"The authorities have crossed a red line. You don't put opponents in prison," said Saakashvili's wife, Sandra Roelofs, as marchers brandished anti-government and anti-corruption slogans as well as banners depicting Poroshenko behind bars.
Saakashvili was president of Georgia from 2004 to 2013 but acquired Ukrainian nationality and served as a governor in Ukraine before falling out with Poroshenko.
"I am very afraid that our government is about to collapse. Ukraine is headed for the abyss, the people are getting ever poorer. Corruption is everywhere and the authorities do nothing," one marcher, Nikolai Sharapa, 58, told AFP.
Ukrainian security services arrested Saakashvili on Saturday following a botched attempt several days earlier when supporters swarmed the van where he was being held.
On Saturday he said he was going on hunger strike in protest at his detention.
"The doctor told us Mikheil Saakashvili is in a satisfactory state (of health) despite the hunger strike he has embarked upon," his lawyer Pavlo Bogomazov told AFP.
Saakashvili is also wanted in his native Georgia for alleged abuse of power.
He spearheaded a pro-Western "Rose Revolution" in the country in 2003 and fought a disastrous war with Russia five years later that eventually prompted him to flee the Caucasus nation.
Saakashvili returned to the spotlight as a vocal champion of the three-month street uprising in Kiev that toppled a Moscow-backed government in 2014 and turned Ukraine on a pro-EU course.
Poroshenko rewarded Saakashvili for his efforts by appointing him governor of the important Black Sea region of Odessa in 2015 before the two men fell out.
