Former Georgian President and former head of Odesa regional administration Mikheil Saakashvili said his life and freedom are under threat.

"I know that both my freedom and my life are at risk... But the existence of Ukraine is at risk, too, and the freedom of Ukraine is much higher than the freedom and the life of one of its citizens, including me," Saakashvili told journalists in Lviv on Monday.

"When I am asked whether I am taking risks, I reply: Yes, I am taking risks," he said.

Saakashvili also claimed that, during a visit to Georgia earlier this year, President Petro Poroshenko agreed with former Georgian Prime Minister and billionaire Bidzina Ivanishvili about opening criminal cases against him. "Poroshenko traveled to Georgia and agreed with Ivanishvili [...] to pursue criminal cases against me. Not a single country in the world will recognize them, and even Interpol refused to pursue these cases," Saakashvili said.

He also said he would decide what to do next after consultations with various political forces. "I am consulting various political forces now. I'll be where they are, and we are working on this," he said.

Earlier in the day, Batkivshchyna party leader Yulia Tymoshenko said following a meeting with Saakashvili in Lviv that opposition political forces were determined to combine their efforts after Saakashvili and a group of his supporters forced their way across the Polish-Ukrainian border on Sunday.

"After all of yesterday's events, all opposition democratic pro-European forces started consultations today to jointly coordinate our actions and combine our efforts with those forces in society that are determined to take the path of establishing Ukraine together and until victory," Tymoshenko said.
